all right folks lets clarify. The tank was a switchover from a 20 long that was up for 18 months. 30 gallons of water,all the live sand and rock,the skimmer and the filter.so basically I added 20 gallons of fresh saltwater to my 20 and put it in a bigger glass box.The Montipora digitata was a freebie and is doing well 5" from the surface.Its only been in there a week and it extends its polyps so we'll have to wait and see on that one.And YES that's a betta sphere on the wall!! if the betta police come they're gonna get thumped!It belongs to my 8yr. old son and he's a brown belt!!Anyway dont fret folks new lights are comming soon...once I build the canopy.I test regularly and all my live stock are doing great in the larger volume of water.
