Thanks everyone for the info, my main concern (which is why I posted another thread about suspected FA) is the fact that it is a small pond that is 3 years old that was tripled in size. The old pond never had any FA. Also the fact that I will be adding fish this month, just didn't want to set myself back with the fish.

3/4 Acre South Georgia Pond, 1,500 BG/RES; LMB coming soon
