Q: What can I do to prevent string algae from growing in the winter?

Laura – Hattiesburg, MS

A: Even in the cold of winter, string algae can grow in your water garden. All that green nuisance needs to thrive is the right amount of nutrients and sunlight. So what can you do to prevent it? You have three options in your pond management toolbox: Seasonal Defense, barley straw extract, and a three-in-one pond tool.

Boost Your Bacteria

First of all, you’ll need to control the nutrients – or the food that the algae eat – in your pond. Because the beneficial bacteria that break down those nutrients go dormant in the winter, now’s the time to add some Pond Logic® Seasonal Defense® (as long as your pond isn’t frozen over, of course). It contains bacteria that prefer cooler temperatures. They’ll accelerate the decomposition of leaves, scum and sediment that feed algae, reducing its growth to a minimum.

Add Barley Straw

If you have a small water garden, like a koi pond that’s less than 10,000 gallons, Pond Logic® Barley Extract provides an all-natural solution for maintaining clean, clear water throughout the winter. Available in bales, pellets and as an extract, it works by releasing compounds that improve water clarity, leaving you a clean and healthy pond. Read more about how barley extract works here. The extract form is easy to use: Pour directly into the water and repeat every few weeks.

Manually Remove It

Should string algae form, you can manually remove it by wrapping it around an algae brush, like the one included in the The Pond Guy® 3-in-1 Interchangeable Pond Tool, and yanking it out of the water. The telescoping handle will add 5 feet to your reach, allowing you to reach those hard-to-access patches of weeds.

Unfortunately, if ice is covering your pond, there’s not much you can do to remove that string algae. Plan on removing it during your spring clean-out process. The sun will return soon enough!

I was out at my pond today and it is still partially covered with ice. I have a de-icer and aeration – isn’t that enough to keep the ice off my pond? | Decorative Ponds & Water Gardens Q & A

A: During these frigid months of the year, a hole in the ice means the difference between life and death for your pond fish. That opening allows oxygen to flow into the liquid water while it dissipates harmful gases caused by decaying debris and fish waste into the air.

Bubblers and de-icers both keep a hole open in the ice, but they go about it differently.

  • Bubblers, like the ones found in Airmax® PondAir™ Aeration Kits, are designed to gently and quietly move the water surface, and that action keeps a hole open in the ice. The aerator also delivers oxygen to the lower levels in your pond while bringing harmful gases to the surface to be released.
  • De-icers, such as the Thermo-Pond De-icer, melt surface-forming ice and create a gas exchange vent in the ice. While effective, during cold windy nights they may not be be enough to keep a hole open on their own.
  • Bubbler-De-icer Combos, like Airmax® PondAir™/Thermo-Pond De-icer Combo, is an energy-efficient option. Because the aerator will bring harmful gases to the surface and your de-icer helps to keep the hole melted, you’ll be sure to keep the ice vent open.

The bubblers, de-icers and combos are not designed to warm the water or keep the entire pond surface ice free. They’re meant to keep an opening for gas exchange, which is all that’s needed for the fish in your pond.

As long as the equipment you have in the pond is sized correctly (see your manual for details on what yours can effectively handle), you won’t need a larger hole. Your fish are less active, not eating and producing less waste, and so they won’t have the gas exchange requirements they do in the warmer months.

If your vent does freeze over during extra cold temperatures, simply pour hot water on the ice where the hole once was. It’ll melt the hole back open – and your fish can breathe a sigh of relief!

We’ve been keeping our fish indoors for the winter and have filtration. Do we need to use any chemicals? | Decorative Ponds & Water Gardens Q & A

Shiela – Norton, VA

A: No doubt your finned friends are enjoying the cozy indoors during the chilly winter season. With your tank’s filtration system turned on, you’re mechanically cleaning the fishes’ aquatic abode – which is a great first step – but there are a few more things you can do to make their stay inside a pleasant one. Here’s what we recommend.

No Chemicals Necessary

Unless your holding tank receives a lot of sunlight, you won’t need chemical treatments, like algaecides or water clarifiers. They’re not necessary, particularly if you use beneficial bacteria, stress reducer and an aeration system.

Boost Your Bacteria

Natural beneficial bacteria, like those found in Pond Logic® Liquid Clear™, will keep your tank water clean (and give your mechanical filtration system a break!), so pour some into the tank. The tiny microbes activate as soon as they hit the water, multiplying every 20 to 40 minutes and digesting dead organics in the water. The result: crystal clear water and happy fish.

Condition the Water

A stress reducer, like Pond Logic® Stress Reducer PLUS, will help your fish enjoy their indoor stay, too. The water conditioner fortifies your fish’s slime coat, which is the natural slime secretion that’s lost when its stressed. It also removes heavy metals, chlorine and chloramines from tap water, making it safe for underwater living.

Aerate and Circulate

In addition to beneficial bacteria and stress reducer, you should also drop in some air stones into the tank and connect them to your aeration system. Because your fish are living in a smaller space, they’ll need even more oxygen than they did in your pond. Our PondAir™ Aeration Kits will infuse the water with plenty of fresh O2 for your fish until spring arrives again!

Setting Pond Resolutions for 2015

Setting Pond Resolutions for 2015

If you were one of the many pond owners plagued by algae, muck, excessive weeds or green water last year one of your 2015 New Year resolutions may revolve around your pond or water garden.

Evaluate

The beginning of the new pond season is the perfect time to evaluate and tweak your pond maintenance practices and take inventory of leftover pond supplies from last year. Since pond maintenance begins once the ice thaws from your pond, there is no better time to start planning for the upcoming season than now.

First, before you buy new pond maintenance products, recall your pond issues from last season. Were you continuously fighting algae? Unsure the last time you applied your beneficial bacteria? Do you have out of control cattail growth? After you identify your issues, pick one or two items to tackle in 2015.

One great product for any pond (earth bottom pond or water garden) is aeration. Aeration is always a great way to keep your pond water balanced and healthy. Installing an aeration system in your pond will circulate the entire water column and keep oxygen plentiful. Aeration systems help reduce pond muck formation and weed growth while keeping your fish safe and comfortable.

If your pond receives constant sunlight, consider shading the water with pond dye. To keep your pond water clear and remove accumulated pond muck treat your pond with beneficial bacteria. Airmax® can help you eliminate the guesswork when choosing the appropriate pond maintenance products by providing the most effective pond care products in one kit. Use the ClearPAC® to treat earth bottom ponds and lakes or the DefensePAC® for water gardens.

Make a Plan

Next, make a plan. Check over any unused pond products from last season. Create a list of any supplies you are low on or anything you are out of. If you are having trouble calculating how much product you will need for season long treatment or have any questions on a particular product you can always call a Pond Guy or Gal toll free at 866-766-3435.

If you don’t have a pond, water garden or water feature yet you can start researching and designing the pond of your dreams now. There is a wide variety of information available on our blog that explain the differences between various water features and ponds. Pond kits are available for purchases that contain all of the items you need to build a water garden. If you prefer something less time consuming, maybe you would like to consider a pondless waterfall. Whichever the case early planning will help make your pond project a success.

When do koi go dormant? | Decorative Ponds & Water Gardens Q & A

Q: When do koi go dormant?

Q: When do koi go dormant?

Helen – Minneapolis, MN

A: With winter officially starting in just one week, the cold weather is settling in across the country. Since your fish don’t have miniature submerged Koi calendars to check, what is it that tells your fish it is time to hibernate?

Koi are cold-blooded creatures, which means their body temperatures and activity levels are directly correlated with the ambient temperature. Koi are active and alert when their environment is warm and will start to slow down as the water temperature decreases. Once the water temperatures start to dip below 46°F your fish tend to stop eating and will retreat to the bottom of the pond. Your fish use the decrease in temperature along with the shortening day lengths as a trigger to prepare for winter.

As the water begins to cool, your fish will become less active as their bodily functions slow down. Less activity means a slower digestive process, less demand for food. It is this decrease in food digestion that warrants the use of wheat germ based foods like Pond Logic® Spring & Fall Fish Food. These types of food are easier to digest that regular food reducing the risk of leaving undigested food to rot inside a dormant fish, which can potentially be fatal.

As the temperatures continue to decline towards 40°F, the blood flow and respiratory rate of the fish will drop to an extremely low rate where their body is hardly functioning. You may hear people say that your Koi are sleeping in the winter and while fish do sleep this goes way beyond the standard drop in bodily functions associated with some much needed shut-eye. This extreme internal slow down ensure survival with even the most limited resources with cases of dormant fish lasting 150 days without food.

The whole over-wintering scenario sounds a little extreme to us but it is truly a natural and normal process for your fish. They do not require much attention in the winter but there are a few things you can do to ensure their winter break is a success. When a layer of ice begins to form over the pond, maintain an opening for gas exchange using an aeration kit or pond de-icer, like the PondAir™ & Thermo-Pond Combo.

Q: If I run my waterfall pump for a few hours a day during winter, will my fish be OK?

Lenny – Waggoner, IL

A: While it may be beautiful to run your waterfall during winter, it is not always recommended. A waterfall pump moves and circulates oxygenated water through the water column, but if you run it for just a few hours each day, your fish – and your pocketbook – may suffer. Here’s why.

  • Oxygen Starved: First of all, your fish need plenty of fresh oxygen, even when they’re semi-dormant in the wintertime. A few hours of circulation from a waterfall pump won’t keep a hole in the ice or infuse enough oxygen into the water, so the lack of fresh air will stress out your finned pals and put them at risk for disease.
  • Ice Dams: If you run your waterfall pump in northern climates during near- or sub-freezing temperatures, ice dams can develop and grow in size, diverting water from the pond. For this reason, you’d need to keep an eye on your water level – particularly if you have a longer stream. When the water level gets too low, your pump could become damaged, which means you’ll need to fork out some cash to replace it.
  • Overstressed Pump: Speaking of replacing a pump, take a look at your pump’s manual. Does it say that your pump is it designed for use in freezing temperatures? Generally speaking, pumps should be at least 2,000 GPH to operate in the winter.
  • Big Energy Bill: The cost of running a waterfall pump can easily top $100 a month. The cost of running a de-icer alone to keep a hole in the ice for gas exchange can cost up to $75 a month. Those aren’t cheap options! An aerator; however, is a cost-effective solution that’ll only cost you around $1.70 a month. In addition, you can use aerators throughout the year.

Because of the risk of damaging the waterfall pump and not providing enough oxygen to your fish – along with the high cost of running it all the time – we recommend removing the pump this winter and replacing it with an aerator.

Stowing the Pump

When you remove your pump, submerge it in a 5-gallon bucket of water to keep all its seals lubricated and store it indoors in a place that won’t freeze. Blow out the water and debris in your tubing with an air compressor and cap it off. Drain the skimmer boxes below the weir door. And spray your filter media off with a hose, pump out any water in the filter box and give it a good scrubbing.

Installing Aeration

Once your pump is removed and stored for the season, install an aeration system that’s sized right for your pond. KoiAir™ Aeration Kits, are designed for ponds up to four feet deep and 16,000 gallons, includes a compressor, airline and a diffuser plate. PondAir™ Aeration Kits are suited for ponds up to two feet deep and 2,000 gallons, includes a compressor, airline, check valves and air stones. Simply connect the diffuser plate or air stones to the compressor, submerge the plate/stones and plug it in, and you’re good to go!

You’ll be delivering oxygen to your fish, keeping a hole in the ice and preserving your waterfall pump – and saving a bunch of your hard-earned money.
