Pond Boss Forums INTRO Questions & Observations Is the cool spring making my FA worse?

Copper sulfate granules dissolved into 25 gal of water, then sprayed over the FA works wonders. But, I'm trying not to go that route this year. I know that there are better choices than copper sulfate, but it was the least expensive option for me plus the water in the pond used to get changed due to it being down belowthe water level in the surrounding ground. No FA problems this year so far. Time will tell tho!
