Thanks!
I have a bunch of tanks to choose from for my sump. It just depends on which one will fit the best under my tank with everything else... I want to set it up in the middle mainly becuase I love semitry... so I dont want to use the 55g cause its too big to fit with the halide ballasts, cleaning supplies, chems, etc... Im either going to use a 29g or a 40g but first I have to sell my 55g, ~35g (Hex), and 12g nano to make money (for 125g) before I can spend more money...
And I definitely need the sump soon! I'm getting a small diatom bloom and with the low water turnover rate it could get out of hand....
