We are currently working on moving from a 90 gallon with a 55 sump (thats pipped in to a 30 frag tank to a 150 cube with a 40 breeder sump. We are building the stand like we did for the 90 as we need more room to fit the sump etc. I am thinking of changing lights, right now we have leds that are working well for most things In the tank but after some talk we are looking at the ATI 8 bulb T5s, whats everyones opinions on LEDs vs T5s.
