My 2 gal has been doing GREAT and is filling in very well. I have C02, aqua base, and a red sea filter and good lighting. I had been using a small amount of flurish in the tanks but for the past two weeks Ive been out of town and the tanks didnt get the flurish. Well... two weeks later the tanks and shrimp actualy look alittle better w/o the ferts.... is it my imagination? Could I have been using too much? & should I just discontinue the ferts all togeather (or the c02) with such a small tank?
