I had previous threads about stockin my 30gal. But here is my plan. Imma sart with a planted crs tank. Then when the crs hit a hudge(thro breedin) number im gonna start to stock my tank. My thghts of stockin it were 2 pictus catfish and 1 senegal birchir. But im unsure if those will actually eat the crs. So i think i mite do exodons. Also wht is the sea chem bottle that raises the co2 in ur tank? Can anyone shed some light on my idea?
