Be Proactive for Long Term Algae Control – Pond & Lake Q & A

Picture of a Pond with an Abundance of Algae.

Q: I’ve treated my pond for algae with one of you Algae Defense, it works great although I have to do it almost monthly. Do you offer anything that would offer longer lasting results? – Jacob of Michigan

A: Algae Defense is meant to be used as a reset button providing quick results. Algae Defense is a great tool to get your pond under control especially during those hot summer months. The disadvantage is that the results are generally only short-term, because it only addresses the result of a problem and not the actual problem itself. To get the long-term results you’re looking for, you will have to take a different approach.

Think of it this way, you only use chemicals, when weeds and algae become a problem. This is a “reactive” approach. You need to think of your pond’s health proactively. Being “proactive” means treating for the problem not just the result of the problem.

Algae and pondweed growth are promoted by two basic things, sunlight and nutrients.

Sunlight can only be controlled by shade trees, surface structure and/or plants or by adding a pond dye such as Nature’s Blue or Black DyeMond.

Nutrients: Nutrients can come from many things such as, grass clippings, twigs, trees, fish waste, yard and farm fertilizers, runoff, etc. The majority of nutrients, especially those that have come from organics decomposing, are found at the bottom of your pond in what is known as black “muck”. The rest of the nutrients are free floating in your waters column sometimes causing murkiness.

Nutrients can be greatly reduced by eliminating “point source problems” such as:

#1 - Leave a buffer area around the pond when you fertilize. Use fertilizers low in phosphorus and/or organic ones.

#2 – Rake your pond using a Pond & Beach Rake removing dead vegetation, leaves and other organics that will eventually decompose on the bottom.

#3 - The next best thing is to introduce an aeration system to your pond and following our proven 4-Step System.

Want to get rid of the Muck FAST? Use all natural, Pond-Clear Pellets. These pellets accelerate the decomposition of “muck”. Depending on the amount of nutrient intake your pond receives, Pond-Clear Pellets can eat up to 5 inches of “muck” per year.
