Just curious if you're going to run the sump that full... and if so, can it handle the back-flow from the display when your return pump is off? There really isn't much room to spare in it now.
Yea plenty of room. I only have the return outlet about a half inch under water so it won't siphon much. I have probably 5-10 gallons to spare after the siphon.
