My pond water is green. Do UVs really work? | Decorative Ponds & Water Gardens Q&A

My pond water is green, do UV’s really work?

My pond water is green, do UV’s really work?
Summer – Baton Rouge, LA

The short answer? Yes. While it might seem like smoke and mirrors, UVs help to consolidate algae particles, which are then removed through regular filtration. And because planktonic algae particles are typically responsible for green pond water, products like our all-in-one ClearSolution™ Filter and AllClear™ systems – which include UVs within their filters – and our PowerUV™ Clarifiers – which can be added inline with your existing plumbing – are terrific resources to help keep pond water clear and clean. Bear in mind, though, that UV can’t work miracles, and has no impact on string algae.

Now that we’ve established the fact that UVs really do work, there’s an even bigger issue to consider. The presence of planktonic algae is, after all, a symptom of a larger issue – and UVs are simply a means to treat it. In order to reduce reliance on UVs and filtration, it’s important to consider the cause of the bloom.

Planktonic algae bloom in nutrient-rich water. Nutrients can come in a variety of forms. There are many culprits – including excessive fish food, an overabundance of fish (and the waste they produce), bird droppings, and even runoff from fertilized lawns. When too many of those nutrients are in your pond, algae – which are present in all water – multiply quickly to take advantage of what they see as a free lunch. When algae multiplies, a cycle begins which depletes oxygen, and can harm or kill both fish and beneficial aquatic plants. So take stock of your pond. Evaluate the number of fish you have – and adjust your feeding levels accordingly. If your pond is overpopulated, consider reducing the number of fish, and the corresponding waste they produce.

Finally, consider using our PondLogic® DefensePAC®, which helps to improve water quality, eliminate muck and built-up debris, and to enhance fish health. With quick and easy application, you’ll see noticeable results in no time – and with minimal effort.

What is This Black Mucky Stuff on the Bottom of My Pond & How Do I Get Rid of It? – Pond & Lake Q & A

Muck Boots Stepping in Muck

Q: What is this black mucky stuff on the bottom of my pond and how do I get rid of it? - Several Customers

A: Over time, organics such as leaves, aquatic weeds or twigs fall into the pond and settle on the bottom. These organics slowly begin to decay and will create a mucky layer on the bottom of your pond. As time passes, this muck layer will get thicker and thicker. Before you know it, you’ll step into your pond and sink a foot down in muck. Muck is also a food source for algae and pond weeds. As the muck layer grows, so will your problems with algae and pond weeds. So how do we combat muck? Below are a few suggestions:

The best way to combat muck is to use a beneficial, natural bacteria called MuckAway™. MuckAway™ is an aerobic bacteria that instantly activates when put into water and will eat away the muck at an accelerated rate. When used with aeration, you can see up to 3-5″ dissipate per year.

Just remember, any organic matter that goes into your pond will create more muck. The more muck, the more food source for algae and pond weeds. Finding ways to reduce the amount of organics going into your pond is a must. For instance, cutting your grass away from the pond, instead of directly in it or removing twigs and tree branches that have fallen into the pond using a Pond & Beach Rake.

One more way to reduce muck is to use a bottom bubbler aeration system. Aerobic bacteria, like PondClear™, will break down muck at an even faster rate when there is saturated oxygen levels in your pond’s water. Aeration also has many other benefits besides breaking down muck, such as clearing the water column of sediments, reducing the chances of fish kills or turnover and eliminating a pond’s thermocline.
