Why is my pond cloudy in the summer and clear in the winter? | Ponds & Lakes Q&A

Q: Why is my pond cloudy in the summer and clear in the winter?

Q: Why is my pond cloudy in the summer and clear in the winter?

Mike – Baldwin, WI

A: Frustrating, isn’t it? During the summer when it’s warm and inviting outside by the pond, the water looks cloudy; when it’s too cold to enjoy the outdoor scenery, the water appears crystal clear. What’s the deal? Let’s look below the water’s surface to see what happens during the two seasons.

Murky Summer

A lot happens in your pond during the warmer months. Fish are actively feeding and creating waste. Pond critters, like turtles and frogs, are digging around in the mud and stirring up muck at the bottom of the pond. Rainstorms wash sediment into the pond along with fertilizer residue – which provides fuel to algae and pond weeds growing prolifically in the summer sun. With all that activity, it’s no wonder the water looks cloudy!

Clear Winter

During the winter, however, activity slows. As your fishes’ metabolism decreases, they fast and hibernate through the cold season. Turtles, frogs and other pond residents reduce their movement, too, which allows the muck and sediment to settle at the bottom. Ice and snow cover the pond, limiting water movement and blocking sunlight. Algae still grows, but at a much slower rate. As everything settles and slows down, the water clears.

Extending Winter

If you want that crystal clear water all year long, follow this three-step formula, particularly as the days get longer and spring warmth thaws the ice:

  1. Feed Your Bacteria: First, be sure to add some bacteria enhancer, like EcoBoost™, to the water. It binds suspended organics, provides trace minerals to fish and other pond dwellers, and helps break down fertilizers from rain runoff. It has no temperature restrictions, so you can use it throughout the seasons.
  2. Shield the Sun’s Rays: Next, pour some Pond Dye in the water. The color reduces the amount of rays that into the pond. Like EcoBoost, Pond Dye has no temperature restrictions, so you can use it throughout the season.
  3. Add Oxygen: Aeration is the final – and most important – step in maintaining clean, clear water. By aerating your pond from the bottom up, you will circulate the water, improve the dissolved oxygen levels in your water column, and allow for increased levels of beneficial bacteria to accumulate in your pond.

My UV bulb was still working when I pulled it out for the winter. Do I still need to replace it? | Decorative Ponds & Water Gardens Q & A

Q: My UV bulb was still working when I pulled it out for the winter. Do I still need to replace it?

Richard – Avon, IN

A:  A UV bulb is one of your best weapons in the battle against discolored water. When those ultra-fine particles are exposed to the bulb’s ultraviolet rays the tiny particles clump together, and those clumps are then removed by your mechanical filtration system.

What’s left behind is clean, clear water – as long as the bulb is working efficiently.

For your UV clarifier to work its best, it will need a new ultraviolet bulb every year. Even though the bulb still illuminates and appears to be working, its effectiveness decreases over time. Your best bet is to replace it when you do your annual spring cleanout, and plan to do so again year after year.

Spring Cleaning

In addition to switching out the bulb, take some time to check the quartz sleeve or glass tube that’s housing the bulb. Does it need a good cleaning? Debris can build up on the glass, preventing those powerful UV rays from penetrating the water as it passes through the filter. Use as soft cloth and a descaler (if needed) to scrub off the buildup.

Filter Check

While you’re at it, check your biological filter media and mechanical filter components, like the skimmer, pump sock and prefilters. Do they need to be cleaned or replaced? Even though your ultraviolet clarifier is tackling most of the discolored water, your filtration system is still responsible for removing the debris. Make sure they’re in good working order before the algae blooms in the spring.

Maintain a Balanced Pond

UV clarifiers do a great job at clearing water, but an even better solution is to maintain a balanced pond the first place. Reduce excessive nutrients by reducing the number of fish in your pond, minimizing the amount of food you feed them and cleaning up the waste they produce, as well as regularly removing the built-up detritus.

My son wanted to know if crayfish can live in our pond. I think they can, right? | Ponds & Lakes Q&A

Q: My son wanted to know if crayfish can live in our pond. I think they can, right?

Mike – Little Rock, AR

A: Yes, those little freshwater crustaceans can indeed live in your pond – as long as you provide the living conditions they need to thrive. Here’s what you need to know about growing a healthy crayfish population.

Home Sweet Home

Also known as crawdads and crawfish, North American crayfish belong to the family Cambaridae. More than 300 species live in rivers, brooks, ponds and even special “crayfish farms” across the country. Most types prefer fresh flowing water that doesn’t freeze in the winter, but some thrive in swamps and ditches.

During the day, crayfish hunker down underneath rocks to hide from predators like fish, birds and alligators. But at night, they slowly cruise the river bottom in search of food. Their preferred meals are anything decaying, including dead insects, worms, algae and fish, but they’ll also snap up small, live fish that are swimming by if they’re feeling too lazy to forage. They’ll also get their greens by gobbling through algae and aquatic plants.

These decapod crustaceans can grow up to 6 inches in length. They’re related to lobsters, crabs and shrimps, and they’re prized cuisine among foodies (etouffees anyone?) and larger fish, like bass and bluegill. Crayfish and dwarf crayfish are also kept as colorful pets in aquariums.

Welcome Residents

Crayfish can make a fun addition to your pond. They nibble on aquatic plants, so they help control weed growth. They eat decaying material, so they – along with Pond Logic® MuckAway™ – will help keep pond muck to a minimum. They’ll entertain your son (and his friends) for hours as they turn over rocks and hunt for crayfish. And they make for some delicious eating for you and your resident fish!

These guys will dig to create burrows in the bottom of your pond – but don’t worry. They won’t likely cause any leaks. It’s important, though, to control their population. Crayfish reproduction is tied to fluctuating water levels, so manage their population growth by stabilizing the water level in your pond, and use basket traps or lift nets baited with meat to remove large numbers.

Create a comfortable environment for crayfish by providing clean, aerated water and some rocks for burrowing. They’ll find their own food – or become food if they venture too close to your Fish Attractor Spheres!

My pond froze over. How do I get it open again? | Decorative Ponds & Water Gardens Q & A

Q: My pond froze over. How do I get it open again?

Q: My pond froze over. How do I get it open again?

Janet – Minneapolis, MN

A:  Brrrr. Jack Frost, Elsa and the rest of the cold-weather crew sure have been busy lately, haven’t they? Despite the use of a de-icer, aeration system and other ice-prevention tactics, long bouts of frigid temperatures and wind-whipped nights can cause ponds to freeze over. And that’s not good news for your fish.

So what can you do? When considering your hibernating finned pals, time is critical. Too long without an open area in the ice for gas exchange could mean dangerous conditions for your koi, goldfish and other pond fish.

Overnight, No Problem

If the pond has been frozen over since last night, your fish should be just fine. Cold, windy nights often cause extra layers of ice to form on the pond’s surface. If your de-icer and aeration are on and functioning properly, some of the ice should melt on its own. Meanwhile, your fish will have plenty of dissolved oxygen in the water to tide them over.

A Week or More, Get Busy

If it’s been a week or longer with no hole in the ice, it’s time to take some action. Without a hole, ammonia and other noxious gases are unable to escape into the atmosphere, and your fish will have no access to fresh oxygen. Here’s what to do when ice overtakes your pond.

  1. Melt It: First, melt a hole back open in the ice by pouring a bucket of hot water onto the frozen stuff near your de-icer or aerator’s airstones. Do not drill through the ice or bang on it with a hammer as this will stress your fish, which are probably already stressed out.
  2. Systems Check: Once a hole is open, check to be sure your de-icer and aeration systems are still running and functioning properly. If not, repair the damage or replace the unit altogether. The PondAir™ & Thermo-Pond Combo, which is an all-in-one aerator and de-icer, works to keep a vent open in ponds up to 2,000 gallons. See the video below for tips on installing the PondAir™ & Thermo-Pond De-Icer Combo.
  3. Reposition Airstones: Finally, if your airstones are positioned at the bottom of your pond, relocate them. Put them in a shallower area that’s closer to the water surface. This will create more movement – and that means a bigger hole.

Should frigid temperatures and a solid ice sheet persist, take a daily trip to your pond to check on the gas exchange hole. Your aerator and de-icer should do the trick, but be ready to melt through the ice if needed.

I occasionally have power outages during the snowfall. Will it cause a problem for my aeration system? | Ponds & Lakes Q&A

Pete – Traverse City, MI

A: Power outages during heavy snowfall or ice storms aren’t uncommon – and when they happen, your aeration system will need some attention. Here’s what we recommend to prevent problems from occurring:

  1. Relieve Air Pressure: Built-up air pressure in the air compressor could potentially stop the aerator from turning back on when the power is restored, so it’s important to get rid of that pressure via the release valve.
  2. Check for Moisture, Condensation: If the power is out for an extended period of time, keep an eye on the cabinet for moisture and condensation. It could indicate reduced air flow, and all that wetness could freeze if temperatures are low enough.
  3. Clear Off Snow: To allow for proper air flow and to minimize moisture from melting snow around the unit, shovel or dust accumulating snow from around the cabinet.
  4. Melt Ice Blockages: Long power outages could cause your diffuser’s air lines to freeze. To melt them and open the air flow back up, pour 1 cup of isopropyl alcohol through each line (or the line you believe is blocked or frozen).

As for your fish, they should be just fine if your aerator shuts down for a few hours. Cold water holds more oxygen than warm water, so they’ll have plenty of oxygen during short-term interruptions.

I have a small pondless fountain that’s cloudy and slimy. What can I use to clean it? | Decorative Ponds & Water Gardens Q & A

Stephanie – Covington, GA

A:  Pondless, fishless water features are known for being low maintenance – but even they get slimy and scummy and in need of some attention. Dust and debris blow into the water, leaves and twigs somehow find their way into the basin, and algae starts to grow on the surfaces. As all that stuff builds up and breaks down, you’re left with a mess.

Good thing it’s an easy problem to manage. Because you have no pond and no resident fish to consider, there’s no need to worry about de-chlorinators, test kits, filtration systems and all that nonsense (although adding a filter always helps, even in a fishless feature). Here’s what you’ll need to do to keep your fountain clean and clear:

  1. Give It a Good Scrub-Down: First, give your feature a thorough cleaning. Shut down the pump, empty the water basin and use a cleaner like Oxy-Lift™ Defense® to break down debris and speed cleaning. Once you’re done scrubbing and rinsing, refill the reservoir with fresh water.
  2. Move It Out of the Sun: Full sunlight will encourage the growth of gunk so, if possible, move your feature to a sun-free spot or shade it from the UV rays with an umbrella or covering. Doing so will keep the fountain cleaner for a longer span of time. Which leads us to No. 3 …
  3. Keep It Clean: Finally, once it’s scrubbed and moved to a protected spot, keep it clean! We recommend our FeatureFix™ & FeatureClear™ Combo. It includes FeatureClear™, which contains concentrated beneficial bacteria that digest organic debris; and FeatureFix™, which eliminates discolored water with a fast-acting formula designed for pondless features. It’s easy to use: Simply remove excess debris from the feature, shake the FeatureFix™ or FeatureClear™ well, and pour into the water. FeatureClear™ works best when temperatures are above 50°F, but FeatureFix™ works no matter the temperature.

Easy-to-maintain pondless water features, birdbaths and fountains allow you to enjoy the aesthetics of flowing water with minimal work, but these simple steps will ensure your water stays clear and your fountain remains slime-free.

6 Ways to Enjoy Your Pond this Season

If you were one of the many pond owners battling algae, muck, excessive weeds or green water last year, it may be difficult to remember why you wanted that pond in the first place. The beginning of the new pond season is the perfect time to do a little research, evaluate and tweak your pond maintenance practices. Getting a head start will allow you to make this years resolution to spend more time enjoying your pond, lake or water feature. Here are just some of the many benefits they offer.

  1. Gives you a nice place to sit and relax: Imagine lounging in a hammock alongside your pond, swaying in the cool breeze. Picture yourself enjoying a cool glass of lemonade while sitting on your dock and watching your fountain cast rainbows against a blue sky. There is a reason why folks vacation at their favorite lake house! You could have one of your own in your back yard.
  2. An investment in your home: Many of us today are trading vacations for “staycations,” and we’re looking at ways to build on our biggest investment, our homes. Landscaping with decorative water features and creating functional outdoor living areas adds value to a home. Plus, it’s fun to add personalized décor to turn the space into your own oasis.
  3. It’s a hobby that’ll grow with you: Keeping a decorative pond will definitely be a learning experience, and as you learn more about the technical aspects of maintaining water quality, keeping koi or aquatic plants, and managing the pump and filter, your pond will look better and better, and bring you more satisfaction as a hobbyist.
  4. Provides water fun for everyone: From paddle boating and swimming in the summer to ice skating and ice fishing in the winter, a pond or lake will be sure to satisfy just about any outdoor adventure. But remember to always play safe, making sure you supervise children at all times and have a life ring and rope nearby.
  5. Creates a wildlife habitat: If you like the great outdoors and all the critters in it, you’ll appreciate the variety of wildlife a pond will bring. Animals of all sorts gravitate toward water. Depending on where you live, you can expect to see wild birds and water fowl, raccoons, turtles, frogs, butterflies and dragonflies, not to mention all the underwater life. These animals will call the pond and your property home, making it an entertaining ecosystem for your family and friends.
  6. Cheaper than therapy: More than one pond owner has told us about how therapeutic their water features are! After a long day at the office, there’s nothing more relaxing than sitting alongside your pond with a cold drink in hand, feeding the koi and pond fish, or appreciating the water lilies in bloom.

Of course, these examples only scratch the surface of the benefits that a pond or water feature can bring to your yard. So take inventory of your supplies and make a plan so you can begin this pond season by relaxing.
