OK, for sake of argument, if the hot would warm the tank up, wouldnt the cold make it harder to heat in the winter? Stupid heaters are already on full time to keep the 300+30ish gallons at 80. I think the heater are an obvious new burden on my electric bill. Ok, maybe part of this is also the sliver of hope that the hotwater will decrease the need for the heaters to run so hard. Dunno, just discussing. The cold side supply really is in the corner and harder to access if I wanted to turn it off, but not really a big deal. If it isnt a hazard chemically, I think I'll try to hot side and see what the effect is. If it can keep the tank warmer without the heaters working as hard then that is a bonus...righ?. If it does cause creep in the summer then I can swap them. Maybe I'll valve both like a faucet so I can adjust cold and hot. Hmmmmm.
On the drain in the sump I am using the existing bulkheads in the side that the return pumps could use. Moved the pump into the sump return chamber becuase the stupid thing was so prone to leaking. Bulkheads werent being used. Now, if the sump starts rising from overfill or something, it will run out the 1" drain on its own. No way to flood the house amymore.......unless something gets plugged. But that far through the sump, a mouse would have to chew trhough the lid and fall into the chamber to even get access to the drain hole.
SMH all of the stuff we do to try and make our aquariums risk and hassle free. Lol
