Hi guys, I'm trying to set up a frag tank linked to my 90 display. I want the flow to go from sump > display > frag tank > back to sump. Shia way I don't need a second return pump. I have all 1inch bulkheads and plumbing.
Problem is once plumbed the syphon wouldn't start from the main tank to the display. I believe it's because where the water comes I to the display I only 10 inches below the exit of the display but it travels 3 feet horizontally so a pretty shallow slope and I have a huge air lock. Trying to adjust the tank and fix the problem resulted in me cracking the tank, old 20g long so a $40 replacement.
So now that I'm starting again from scratch should I change the way I have it set up? My overflow from the frag tank is perfect it's just getting that syphon to start that's causing issues for me
