    I have built my own tank - originally I had a Fluval Fx5 External filter 1500ltrs but because water level in sump is lower than the top of filter, filter was constantly sucking in air and stopped working. So I need to replace with a sump pump. *Attached photo's* Main Tank = 191 UK gallon -...

    Finally setting up my refugium/sump. Concerned if siphon is broken or blocked, display tank may overfill. Please advise product to turn off pump if tank starts to overfill. I was going to buy another Auto Topoff unit (ATO) but they are programed to turn off after 3 minutes (17 max).

    I don't have a pre drilled tank but would like to use a sump. Are the over flow boxes safe to use, or what happens when the power goes off and the sifen is lost. Do I need the sump in the first place. I'm getting conflicted advise and need to narrow it down. My tank is a 1 week old reef tank.
