Well the the journey continues, I will replacing the 90 gallon with a 180 gallon and will be moving the 90 gallon above the the sump in the fish room. Few questions 1: what is a good way to make a stand for a tank with the same foot print ( I want to put the 90 above the 75 ( same foot print). And 2: I would like to up grade my pump, what is a good pump with warranty that would do the flow for the 180 and t-off to the 90 for a frag tank?
