Tetra used to put out a medicated flake, NOT the sticks you can still find. It worked pretty good in a reef situation if you could stop feeding everything else and just use the flakes. The problem is they quit making the flakes. But you may still be able to find some cans on the self in some stores. I was lucky enough to find some at Darby's on I-35 a while back, but I bought the last 3 cans they had. It might be worth a large group like this to send a request to Tetra to get it back on the market because the stuff is really helpful. :grin:
