My tank, well Im building a freshwater display for myself 600-1000gallons, dont have a reef right now. Took my tanks down due to poor health, Ive built many tanks of all sizes. Most were around 300-800 gallons, then a few in the larger range 2500 gallons and up to 7500 gallons. I built custom setups for a living. Havent worked for a couple years now. Now that my health is comin around, Im gona get some tanks going again, starting with a freshwater display.
