Your tanks look pretty good. Are you going to qt the powered blue. If so then hes got a good chance of not making it. Powered blues are very picky with water and need to be qted so ich isn't brought into the tank and make its way to the tang.
i was thinkin bout getting that light but lfs said i would need a chiller because it would heat up the water to much. have you had any problems with it?
not much, since its off the water 6" or so, and it has a good fan. But u need to clean it weekly. At least for my tank, it rasies the temp to 78-79 degree without a heater, i think now thats it cold and the house it keep at 68-70 the heater kicks on every now in then.
also lfs prices on orbits are crazy
