Today the temp outside was up to 74 (highest since I set up my tank), and inside was up to 76. My tank went up to 80 degrees. It's winter - what will it be like once summer gets here? Makes me think I better start looking at chillers. Does anyone have a suggestion for an appropriate size chiller for the 130D? I was looking at a MarineDepot catalog, and it seems that the chiller could cost almost as much as the tank did!!! Does RSM sell a chiller? Maybe I should check their website now, but I would still appreciate suggestions. Would a Nano chiller be enough?
