I I just got a couple of bags. It's a little more $$ than the AM500, but not too bad. I'm hoping the YP, will adapt to it. I know it's a BG formula, but I thought I'd give it a try. Besides, I have HBG in the pond now. Along with some HSB, and SMB. (From Rex)
9 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these. I think that's about all I should put in my little pond. Otter attack in 2023
