Making a 20 gallon acrylic 'fuge!

[Palytoxin]

Well, title says it all, I'm currently building a 20 gallon refugium for my 20 gallon tank. I've been studying refugiums for a while and sumps are cool, but I think a standalone refugium > Sump would be best for me considering my tank is mostly home to mostly zoanthids and a single clown. No plumbing or drilling holes on the tank. I intend to have piping going up over the tank for the intake/out take and using a powerhead to kickstart it when need be and gravity will take care of the rest. Btw, Using E6000 for the acrylic to acrylic bonding.

Only Issue I'm truly having is how to set an auto shut off for if the pump runs dry in case water level in main tank gets too low.

Following! E6000 is pretty good for a plastic to plastic glue but why not use an actual acrylic welding product?

Well, I'm brand new to making really anything. So bonding acrylic to acrylic was a new start for me. I figured I would give the e6000 a try considering it was the easiest product to pick up. So far it seems it's holding well, just have one more piece to bond, then I'll be using acetone in order to remove any residue then time to flush it for about 24 in order to test + remove any sort of chemical residues.
