I'm planning to locate my sump, refugium and frag tank, etc. in a remote room off my garage, on the same floor, about 35 ft away, but plumbing must go up in the ceiling of the garage and over to the remote room. The remote room was previously used as a dark room with a sink and climate controlled.
Plans include a stacked array set up much like yours with the return coming from the top.
I plan to control potential overflows with redundant float switches, adequate tank volumes and syphon breaks in the event of pump failure or power outages.
Plumbing between sumps will use 1" insulated pvc
Any suggestions would be much appreciated.
Thank you,
Elliott
