Esshup,
34# in a .8 ac pond!?! They should do a number on that stuff. I believe in 'em now for algae control, but here is what I "think" is happening..I don't think I started seeing results until they started breeding, I think that maybe the fingerlings or little ones have been devouring the stuff (algae) and this is why, I was at the Pond tonight and I was looking at one of the last remaining small FA mats near the bank on the very shallow end of the pond (it was about 4'x4')I saw a Tilapia sitting off to the right of this FA mat, the large one scurried off when I went closer to look, and when I did look I observed (guessing) one hundred of small Tilapia diving in and out of the mat, I also noticed the larger Tilapia return as if it was guarding the small ones...Was it the small ones gnawing away at the FA mat like termites? That's what it looked like to me....I dunno? Is this how it works?
