I was planning a 65 but ive been trying to talk my wife into a 4' tank. If 4' I'm between a 75&90 not sure which yet. I'm pretty close to getting approval so my question is should i buy reef ready or drill for a glassholes overflow. If I go with the overflow should I go with the 1500 gph or the 700. The 1500 is only $20 more and I won't have to worry about dialing back a pump. What does everyone think?
