your tank looks good! any idea what kind of fish your gonna put in it? i wanna make one big sump for both tanks. i have one big 2400 gph pump that will run both tanks. trying to cut down on electricity as well. im just trying to decide wether to buy a sump or make one. i made the one for my salt tank but not sure if its worth buying another tank and all the acrylic and stuff to make one or if its just worth buying one. for a sump that can handle the 310 gal its almost $400. and if building ones only gonna save me $100 its not worth the hassle. whats your thoughts? what do you run for filters? i have a fx5 and 2 emperor 400s 0n my 135 at the moment but honestly im not a fan at all with the performance of the fx5.
