Trying to stock my 72 with some little crawlers, but I dont know the best way to go, JL Aquatics doesn't answer their phone (crazy ass Canadians), ISPF doesn't have strictly a "clenup crew" kit, and I want more snails/crabs than they provide with their mix n match. inland has the same prob as ISPF, cause I am looking for 40-50 snail and the same in crabs, blue-leg or scarlet. I must act fast because my halides are creating quite an algae fiasco in my tank, and the few critters from my LFS aren't hackin it. Hurry, help!! ???
