not sure if it works for fa or not. we use it on occasion and in the past even more to bump up alk for a short time to make it easier to fertilize. However in SE water if you use more than 100 lbs/acre ( UGA pond manual states 50 lbs.) you could casue a fish kill, it is very basic pH I think aroudn 11 so be careful.
