Tanks finally set up with sump

[Starry]

Yeppers, when I turn everything off the water level rises about 2". The tank is 16" deep and the high water level is 12" so that leaves me 4" of flooding space. I'm also gonna drill a hole just below the tank water line on the return just in case the check valve should ever fail. If the tank level ever drops below that hole, it will suck air and break the siphon to the sump.
