As time goes on there are a few things I would do differently with my setup. One is install a intake bypass in my sump area. This weekend I did a water change and after I was done I plugged the main pump in and it would not start AGAIN. This happens every once in awhile I is generally because some gunk need sto be removed. So I installed a bypass so no I never have to unplug the main pump. That would have been a much easier job in the beginning. Aonther is install single end MH instead of the DE. I do not know if there is a difference in outout. But I have 250 DE and replacing the bulbs involves 2 people to lift the heavy canopy off the tank. Making sure all the wires come with it, big pain. The old fashion screw in bulbs would be so much easier, and I can get Radiums, I think they only come in SE at 250.
