This is what I'm thinking of, and I'm open to criticism and advice. 50 gallon tank 20 gallon sump 400 gallon protein skimmer 400 gallon filter penguin 660 powerhead 70 pounds of live rock, some in the sump 3 inches fine sand glass heater 1x flourescent system 1x stronger light system. possibly try some LEDs fr the Reverse photosynthesis planning on running what is referred to as revers photosynthesis in the sump, which is actually really simple. I know metal heaters are of higher quality, but don't think there necessary if there in tank. of course, if it's necessary I'll put it in. I'll probably dose with something to keep the alkalinity in line.
