Large ponds have special challenges when you’re dealing with an algae problem. Compared to small ponds where you can remove some of the stuff pretty easily, a large body of water doesn’t always make this all that easy.
Although there are similar reasons why algae might thrive in any pond, the fact is that large ponds are normally affected by environmental factors more than anything else.
In the video below we’ll cover, step by step, the process that we go through in dealing with algae in a large pond. Our goal is simple. Look for anyway to turn the pond around without resorting to the use of chemicals. Sometimes this can’t be avoided but many times it’s very possible to avoid an algaecide altogether.
Here’s a couple of follow up notes. You’ll hear the term beneficial bacteria mentioned. There are many kinds you could use, and in large ponds we break these down into muck reduction bacteria and pond wide cleaning bacteria. These are targeted for various problems and while we may combine them from time to time, they can also be used individually to good effect.
Many people love the idea of ultrasonic algae control and it does work well on large ponds, however it’s very specific in what it can work on. We have now instituted a rental/trial program on most of these units so that someone can actually see if the technology will work for their particular situation, rather than just buying a unit outright and hoping it will work. Like most algae control measures, it alone may not be adequate to deal with every problem but when combined with other sensible measures, it can help to turn a pond algae problem around.
