I just bought a 72 gallon bow front for $50 with base. I currently have a 10 gallon tank with 2, convicts, 2 fire mouths, and a pleco. These fish are growing and need more room. I have ordered an AC110 and planning a play sand substrate. I'm going to pull some water from my 10 gal and my buddies 75 gallon to get it running. I'm also going to move over my finless fire mouth so he can heal up or die in the cycle process. I was also thinking of putting in the ac110 one of my friends used media to assist. What do you all think, and suggest? Thanks.
