I found a pretty big supply of Aquamax near me in the St Louis/Washington Missouri area. I grabbed three bags of the max grower 600.
I asked the dealer how he had so much in stock. They said they have a customer that goes through 7 bags per day! shocked
They have to keep him supplied, as he's a commercial fish grower. There's a guy that build a pond not too far from me a few years ago. He's got huge docks that go up and down, and aeration going all over it. I think it's the same guy that needs the 7 bags per day. He sells a lot of tilapia (I think.) commercial operation.
At least it's out there. If someone needs a bag or two let me know. I'll have to ship it or meet you near St Louis.

12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
