Right now I am dropping water lines from my aquarium sump to the basement below it into a pump which pushes the water through my chiller and then back into the tank. This is all in my shop, which is sometimes dusty. I have filters and doors on the chiller cabinet, but when closed, the chiller gets pretty warm so unless I am doing woodworking, it is open. I have a store room in the basement that is approximately twenty feet away from the chiller/pump. I would have to run over ten feet and then across 20 feet and make my drop to set up a refugium, skimmer etc. station in that room. That room has a drain, sink electricity, etc. Do you see any problems in this idea? I think a bigger pump would probably be in order, and probably some check valves (probably should have these anyway), but anything else? My lift would only increase by about three feet.
