The bigger the tank the better, right? If I COULD get a 55, should I? I am thinking about after its done I could make it a fuge. And then for new fish just detach it and use it as a QT. Would that work? Also, I would be worried about the water not being cycled so COULD I use the water from the display? Would ick get in there anyway? And even if it did it would just die right? Also, do you just use a HOB filter rated for your size tank? Larger is better I know, but would that work? Also, I should do pwcs every day to every other day? Correct? I would use hypo, and bring it down to 1.010. Is that right? Also, no substrate or LR, just pvc? Thanks for all the help so far.
