How to prevent flood during black out???

[GQ22]

I guess i am playing with fire , but my set up is such that i have two sea swirls which siphon out 4 inches from my tank bck to my sump when there is no power. Ive seen this happen when i turned off my return to do some maintainence. How do you prevent such a dilema?

Get rid of the sea swirls or get a bigger sump. You maybe able to drill a break siphon hole jut below the water line(I've never done it on a seaswirl). Your setup should be fail safe without being dependent on power, not that you said your sump can't handle the 4" of tank water

DOH, I forgot about check valves. Be sure to plumb it so you will have access for cleaning.

I have a 72g AGA bow front with CPR CY194. We have quite a few power outages here in nassau and I never had a problem with overflows.....until I took the filter apart for a much needed cleaning out of detritus that accumulated in it about a month ago. After I put it back together and did a bi-weekly maintenance siphoning out water, to my horror, I just happened to look down for some reason at my 194 and saw the water level was just about to overflow and I quickly turned my system on to lower the level. I have not one clue what I did to cause this. When I shut the system off, I look in the back where my sump/return pump is located, and I see the water level rising...sometimes stopping either 7/8 from the top or 3/4 from the top. Does it have to do with my return head? Is it suppose to be above the water or below the water line so there is no back siphoning?
