Should I eradicate all algae from my pond? | Decorative Ponds & Water Gardens Q&A

Should I eradicate all algae from my pond?

Should I eradicate all algae from my pond?
Suzanne – Arlington, VA

In a word, the simple answer to this question is no. Algae serves a vital role in the health of your pond, providing both natural filtration and food for fish and wildlife. Algae also looks aesthetically pleasing in a pond, provided there’s not too much of it.

To better understand algae’s place in your pond, it’s important to know the different types that are common. First, there’s filamentous algae. Often referred to as “pond scum,” growth of filamentous algae typically begins on the pond bottom. As it grows, it rises to the surface, and can quickly spread to cover the entire pond if not controlled.

String algae is the second variety of algae pond owners will invariably come to know. Essentially a variation on filamentous algae, this algae isn’t harmful, but its rapid growth can quickly take over the pond if it’s not controlled. Frequently seen on rocks in waterfalls, string algae has been known to double its mass in 24 hours when conditions are right – leaving little room for beneficial algae growth, and inhibiting the growth of beneficial bacteria and plants.

Where filamentous alga are generally unwelcome in most ponds, planktonic algae is its beneficial counterpart. Planktonic algae generally thrives within the first few feet from the surface, where it relies on light for photosynthesis – and produces food for microscopic pond dwellers and newly-hatched fry. While typically desirable in ponds, planktonic algae can bloom, and some forms can be toxic to animals. In those circumstances, special measures may be necessary to control its growth.

In order to maintain a healthy balance of algae growth in your pond, there are a few simple steps that go a long way. First, consider our Airmax® KoiAir™ and PondAir™ Water Garden Aeration Systems to ensure sufficient aeration. Stagnant water is an open invitation for excessive algae growth. Even if you have a waterfall, consider adding one to increase water circulation. For more aggressive algae treatment, our an algaecide such as AlgaeFix® to kill the algae and then follow up with the Pond Logic® DefensePAC®. And as a precautionary measure, consider adding a selection of Aquatic Plants to help maintain your pond’s equilibrium, to reduce excessive algae-promoting sunlight, and to provide safe havens for fish.

What do I do to clean out my water garden now that the snow melted? | Decorative Ponds & Water Gardens Q&A

What do I do to clean out my water garden now that the snow melted?
Brett – Delta, IA

Spring is the perfect time to perform a clean out on your water garden or decorative water feature and remove accumulated growth and debris from the winter months. Not only does this result in a cleaner better looking pond, it also promotes a smoother transition into the warm summer months where a unbalanced pond can easily be overrun with green water and string algae.

Once the ice melts from the surface of your pond you can begin your cleaning regimen. Start by pulling out as much muck and debris as possible. You can use a Interchangeable Pond Tool to safely remove your decorative pond fish and sweep debris away from the sides of the pond. Pond Vacuums are a great way to siphon muck and debris from hard to reach areas of your pond without the hassle of bending and scrubbing. Sprinkle Oxy-Lift™ Defense® on your waterfall rocks and stream bed to lift stuck on debris without having to scrape at your rocks and liner.

After the majority of debris are cleaned from the pond you can perform a partial water change by removing around 20% of the ponds volume and replacing it with fresh water. Not only does this refresh the pond water, removing water from the pond with a pump or bucket will also eliminate some of the floating debris you kicked up during the cleaning process. While the pond is refilling mix in some Water Conditioner to remove the harmful metals and chloramines found in well and tap water.

Remove your Filter Media Pads from your waterfall filter, skimmer and pressurized filters. Inspect them for signs of wear and tear and replace accordingly. Thoroughly rinse your filtration media to remove built up debris. Apply PL-Gel to your new or cleaned filter media to seed them with beneficial bacteria and place them back into position.

Now that the pond is cleaned up and topped off you can start up your pumps and begin circulating the contents of the pond. Inspect the pumps, plumbing and power cords for signs of wear, cuts or leakage. Check your waterfall and streams for out of place rocks, splash-outs, and misdirected water. Black Waterfall Foam can be used to keep rocks firmly in place and route water where you want it. Inspect your pond liner for leaks and check the perimeter of your pond for damp areas or puddles.

If the water is still below 55 degrees apply your Pond Logic® Seasonal Defense® to balance the pond water and introduce beneficial bacteria to the water column. If the water warmer than 55 degrees you can apply your Nature’s Defense® instead. The Pond Logic® DefensePAC® bundles the water treatment and maintenance products you will need for the season while providing a price break compared to purchasing products individually.

Let the pond water circulate for a couple days before re-introducing your decorative pond fish back into the pond. This will give the pond water some time to balance without putting unnecessary stress on your fish. Add some Stress Reducer PLUS to the water before you start acclimating your decorative pond fish back into the pond as it will help supplement their slime coat and reduce exposure to stress and harmful residual water contaminates.

While it requires a little elbow grease up front, a thorough spring clean out will save you time, money and hassles later in the season so you can spend more time enjoying your pond while the weather is nice.

Kathie – St. Cloud, MN

It is about time to get your pond up and running for the season. Your decorative pond fish may be even more excited than you are if they’ve been stuck inside for the winter. Before you re-introduce them to their pond you will want to give it thorough once-over to make sure the pond is healthy, clean and ready for spring.

You may choose to perform a complete pond cleanout and start from scratch, or if you prefer you can leave the pond in tack and just do some minor preparations. If this is the case, start by removing debris and algae from the water column, stream, rocks and pond bottom. Dusting Pond Logic® Oxy-Lift™ Defense® on your rocks and waterfall will lift hard to remove debris and save you the time and energy of having to scrub them clean. You can don a pair of Aquatic Gloves or use a Pond Vaccum and go to work removing the muck and debris that have sunk to the bottom of your pond.

Once you have removed as much solid debris as possible you can perform a partial water change of around 25%. Include a dose of Pond Logic® Stress Reducer PLUS or Water Conditioner to neutralize harmful water contaminates. Inspect your filter media for signs of wear and tear and replace as necessary. Thoroughly rinse off soiled filters and seed them with PL Gel Bacteria so they are ready to work as soon as you reinstall them in your filters. If you brought your Pressurized Filters, UV Clarifiers and Water Pumps inside for the winter you begin to bring them out and install them now. With your pond cleaned out and filtration system in place you are ready to fire up your pumps and circulate the water in your pond. Add your seasonal cool-weather bacteria like Pond Logic® Seasonal Defense® to further establish beneficial bacteria in your filtration media and pond.
Let the pond circulate over the course of a few weeks if possible before adding your fish. This will ensure your fish don’t suffer from peaks in pH or ammonia while your water finds a happy balance. Ideally temperatures over 50 degrees are more easily adaptable for your fish but be sure you acclimate them to the pond slowly following the same process you would to introduce a few fish. Using Pond Logic® Stress Reducer PLUS will aid in this process.

A good spring clean out will set the pace for your ponding season and prevent future headaches and stressed fish. Be patient and thorough using the proper tools so you can make your pond even more enjoyable this coming season.

How can I get rid of the discoloration in my pond? It looks like a tea pot. – Decorative Ponds & Water Gardens Q & A

Tea colored water is a common issue that typically comes up later in the year as the weather cools and the trees start to drop their leaves. The ponding season may be coming to an end in a couple of months but you still want your pond looking its very best. Where is this tea colored water coming from and how can you make it go away?

Water discoloration can occur for a couple of reasons both pertaining to organic debris having a significant presence in your pond. If you have a lot of floating organic particulates in your water they will cause turbid or colored water and is usually stirred into the water column via your pump or aeration system. The other cause of water discoloration, and the most common cause of tea colored water, is the presence of an abundance of organic debris. Leaves are the main contributor to the problem as they release tannins into the water which, like you said, leaves your pond looking like a tea kettle. The best way to determine if your pond suffers from floating particulate or an abundance of tannins is by filling a clear jar with pond water and placing it in a still area. Floating debris will eventually sink to the bottom of the jar leaving the water clear looking. If the water is tinted by tannins the water will remain discolored. Once you pinpoint the culprit you can effectively treat the problem.

Since an abundance of organics is to blame in either scenario you will want to start by cleaning the bottom of the pond to remove any muck, leaves and any other remaining debris. The easiest way to do so is to use a Pond Vacuum but if you do not have one yet a Skimmer Net, Gloves and elbow grease will do the trick. Once you have the majority of debris cleaned out of the pond you will want to do a partial water change. Physically scoop or pump out 10 to 25% of the contents of your pond and fill it with clean fresh water. If you have fish in the pond you will want to add Water Conditioner to detoxify the harmful components of tap and well water. If you are fortunate enough to be enjoying warmer weather still and your water temps are above 50° add Beneficial Bacteria to digest remaining organic debris and to keep them from accumulating again. Using Muck Defense® goes a long way in removing hard to reach bottom dwelling muck from between your rocks as well. If your water temps are below 50° substitute your beneficial bacteria products with Seasonal Defense®. To remove tannins from the water place a media bag filled with Activated Carbon in your biological filter. While the bacteria and activated carbon are going to work you may want to consider covering your water garden with a Pond Protector Net Kit or some Pond Netting to keep new leaves and debris from making their way into to pond. A cleaner pond going into the Winter is much easier to maintain come Spring time so a little work now will go a long way later.

Should I vacuum my pond? – Decorative Ponds & Water Gardens Q & A

Should I vacuum my pond?

Should I vacuum my pond? Heather – Landfall, MN

Regular pond maintenance throughout the ponding season ensures clean clear water. An extremely lucky few may find themselves in a scenario where their pond is perfectly balanced with no debris blowing into the pond and no layer of muck developing at the bottom of their water feature. Then there are the rest of us who deal with slimy gravel or decomposing leaves and fish waste yucking up our ponds. Pond vacuums are a handy tool to make pond cleaning manageable and easy by physically removing hard to reach muck and debris from within the pond without bending or scrubbing.

While there are a number of vacuums available for purchase, the best type for you will depend on the size and type of pond you are trying to clean and what you are trying to clean out of it. If you have a small pre-formed pond or a fountain that you need to remove debris from then a small water-driven vacuum may be the perfect fit. An example of this type of vacuum is the Laguna Pond Vacuum Kit which consists of a water-driven vacuum head and hydro brush attachment. Water-driven pond vacuums attach to your garden hose and use the water flow to create suction. A mesh net placed behind the vacuum is used to catch debris.

If you are looking to clean out fine silt-like debris or have a large water feature you would be better suited with a motor driven ClearVac™ Pond Vacuum. The ClearVac™ can plug into a standard 110 volt power outlet and use a motor to create suction. This type of pond vacuum carries water and debris through the vacuum hose and into a reservoir which can then be discharged outside of the pond through a drain hose. It comes with extension handles and a full arsenal of attachments to clean hard to reach areas of the pond. The ClearVac’s™ dual chamber system, rugged wheels, and powerful motor make it the ideal vacuum for those of you with large water features as it is easy to maneuver. The dual collection chambers cut your cleaning time as the vacuum never has to shut off to discharge. Once one collection chamber fills the vacuum switches to the empty chamber and continues to work, emptying the filled chamber in the process. If you have gravel or stones at the bottom of your water feature using one of the vacuums smaller attachments will keep you from sucking up stones along with your muck. If the bottom of your pond consists of dirt or fine pea gravel you will find yourself spending more time cleaning dirt and gravel from your pond than muck and debris. You may want to consider implementing a different substrate material or just focus on using Muck Defense® bacteria to help digest bottom dwelling debris.

How do you spot a sick fish? – Decorative Ponds & Water Gardens Q & A

How do you spot a sick fish?

How do you spot a sick fish? Sharon – Romeo, MI

You treat your pets like children so it is easy to understand how upsetting it can be when one of them falls ill or does not feel well. While your children are able to tell you where it hurts, it is a bit more difficult to figure out what ales your fish. For this reason alone it is a great idea to focus on prevention instead of waiting to cure. What can you do to prevent fish illness and how can you tell if your fish may be coming down with something?

Keep your pond clean and healthy by providing adequate filtration, aeration, and regularly cleaning and adding beneficial bacteria to the pond. A DefensePAC® is a great tool to help maintain water quality and a Pond Vacuum cleaning your pond easier and more enjoyable. When performing water changes use Stress Reducer PLUS to detoxify any chemical or heavy metal contaminates in the water as well as reduce fish stress and improve their slime coat which makes them less susceptible to disease. Dosing your pond with Pond Salt will also help improve their slime coat and gill functions further ensuring healthy and happy fish.

If your fish still manage to fall under the weather the will almost always show some inconsistency in their behavior that will give you a clue as to what is going on. When fish are stressed or ill they will tend to be lethargic and less social, often just floating in one area away from your other fish. If they have anchor worm you will see them rubbing on rocks or the wall of the pond which is known as flashing. You can also visually inspect your fish for signs of illness. Deterioration of their fins, mouth or gills can indicate poor water quality or parasites. Look for loose or odd looking scale formations and sores on the body of the fish.

There are three steps to follow to nurture your sick fish back to health. First, since most illness is due to stress or water quality in their environment you will want to provide some temporary relief from the source. Start by performing a 25% water change in the pond to get some fresh water into the system. If only a few fish seem to be affected you may also choose to set up an isolation tank and treat just the affected fish. Next add salt and be sure both the pond or isolation tank has adequate aeration.

Step two is to identify the fish sickness based on their symptoms. Take pictures, examine the fish for and cuts, redness or inflammation in the gills and record their habits. Once you’ve identified the symptoms you can choose the next course of action which may involve additional medications or treatments.

The final step is to reevaluate your normal pond routines. Go back to see if there is anything you should change to prevent illness in the future. When dealing with sick fish it is always important to focus on preventing issues before they have a chance to ruin your ponding season so you can spend the majority of your season playing with your pets instead of playing doctor.

Spring Accessories – Decorative Ponds & Water Gardens

Dyed Pond

Behind The Springs
It is truly an enjoyable experience taking in the sights and sounds of a water garden. Crystal clear water, brilliantly colored fish and lush green plants all meld together to create a picture perfect landscape. While water gardens are a wonder to behold, pond guys and gals everywhere are working hard to keep them looking their best all season long. Let’s take a behind-the-scenes look at some of the accessories that make that work a little less… well… hard!

What’s Your Net Worth?
Having a pond net handy for regular maintenance is a surefire way to add some ease into your cleaning regimens. Purchasing a tool like our 3 in 1 Interchangeable Pond Tool not only allows you the ability to skim floating debris from your water gardens surface, but also gives you accessories you can use to round up and relocate your fish for large scale clean ups and to clean seasonal build up from hard to reach surfaces. The added benefit of a telescoping handle ensures that the areas you need to clean are within reach. Remember, the objective of using tools is to make work easier on you. Purchase items that perform for you and work best for your specific situations.

Sayonara Sludge!
Giving your water garden a thorough cleaning in the Spring will help reduce the chances of dealing with excess algae growth and overall improving the quality of the water in your pond. Simplifying the cleaning process using the correct tools encourages us to perform our cleanings a bit more enthusiastically. While Spring cleaning is not the most enjoyable pastime for water gardeners, it can be way more convenient (and way less painful) with a pond vacuum. Vacuums like the ClearVac™ clean the built up muck from your ponds bottom while eliminating time spent bent over scooping and scrubbing. Adding beneficial bacteria like Pond Logic® Nature’s Defense® & Muck Defense® when your water temperatures reach 50° or higher will naturally break down organic debris that eventually turn into muck at your ponds bottom. Preventing sludge build up will result in easier and less frequent cleanouts throughout the season.

Using Some Colorful Expressions
So maybe this is your first season, or you are looking to add a special touch to your water garden. Implementing a variety of aquatic plants and shoreline grasses will add some color to the landscape and will have a positive impact on the water quality in your pond. Floating plants like Water Hyacinths or Water Lettuce will consume the same nutrients as algae that are present in the water column, reducing the amount of food available for potential algae blooms. Submerged plants like Hornwort give your fish an excellent place to hide. Try to include a diverse selection of plants to boost your water garden’s visual appeal and promote a balanced ecosystem.

Another great way to accent your water feature is to install pond lighting. When it comes to shedding some light on your project, it can be as simple as adding a couple Solar Floating Lights to set the tone, or installing a series of Waterfall Lights and some LEDPro™ High Output Lights to highlight the surrounding landscape. With a wide assortment of lighting styles to choose from including Halogen, LED, and colored bulbs, you can achieve a unique look that fits exclusively to your pond!
