The lights i have been running are just pc's, i had no plans to turn this into a reef tank but to just have it as a FO with live rock and fake corals. There is a UV sterilizer, Oceanic wet dry system made custom for the tank with a built in protein skimmer. Everything is ready to go, the tank is drilled on both sides perfect if you would like to turn it into a reef. I just need this tank gone. I think i may be able to sell the puffer to a friend in no one is interested in this beast of a fish. Once again to let everyone know i am taking a major hit on this tank but i dont mind because things happen and i just dont have the time and effort anymore, there is also bunches and bunches of food and other neat stuff that comes with the tank as well.
