Ok I am leaving next week for a little less than two weeks. I am going to Florida. I will be spending time in the keys (if anyone knows a good place to go for scuba or snorkeling let me know) I will be gone for two weeks so the thing I am worried about is the water evaporating in my sump. My tank is biologically run by my live rock only and protein skimmer. My tank has 2500gph in a 150 gallon tank. My sump only makes up for 800gph of that total. So if I don't want to have someone comingto my house can't I just shut off my sump while I am gone??? I would still have roughly 12 x turnover in my tank with only the powerheads in the tank. The skimmer can be off for two weeks I am not so worried about that. (people run their tanks forever with no skimmer mine will be fine without for two weeks). Is there any problems with doing this???? Like there will be some water sitting in the sump will that water go bad or anything??? like should I have a powerhead circulating the water in the sump as well??????
