    Dirty Water

    By Koiqueen on Jul 19, 2020

    I have a very large pond w/two waterfalls and an over population of over sized fish. I use this every time I clean the filter and it really breaks down the waste and helps keep the water clean. I have to use more than the directions suggest to get the necessary results. And I don't have to travel I have a very large pond w/two waterfalls and an over population of over sized fish.

    Better with other product

    By on

    Do not expect this product to clear the pond water by itself. If sprinkled on the water, it ends up in the filter eventually. It seems that sprinkling the powder in the cascade helps mixing with the water. It works better with an algaecide, but in summer, even with the enzymes and beneficial bacteria, UV light and copper ions, the sludge and algae can only be controlled. Still somewhat helpful.
