I was at a pet store when i saw a 8 gallon biocube on sale for 75 bucks. Its brand new in the box still, i just didn't know if it was a good deal, and also what the quality was on the biocubes and if people have had good experences with them. also the lights it comes with "Coralife 10,000K 18Watt Compact Fluorescent lamps" what kind of corals can i keep with that? pretty much everything or is there a limit to it. THanks
