Totally indoors so temp isn't a major concern. Already taken over a corner of the basement, insulated the grow bed room and started experimenting with an auto overflow dumping into a swirl filter so I don't have to drill a 150g tank and learned how to overdrive a fluorescent fixture. I HAVE discovered that the pump that I have simply isn't going to cut it - free isn't always good
. BARELY handled a 50' run of hose with all of 2' of lift so I'm probably going to go with a submersible in my sump to take advantage of any heat transfer. Basement usually stays 65-70* year round so I'm hoping the tank won't need much insulating. Figured I'd check around locally, first, as overnight shipping is what usually kills deals. Fortunately, I've got some time as I'm redesigning the grow bed due to a liner failure so I'll still have to cycle up after re-build. So I'm a good month or so away from fish but figured I'd start throwing feelers out now.
