Keep sump from over flowing?

[ozorowsky]

Hey everyone,

What are your tips/tricks to keep the sump from over flowing? If my power gets cut to my sump, the refugium fills up pretty good.

I heard some people drill an air hole in the line near the top?

Do you just place the return high in the tank so if it over flows not a lot of water gets sucked in?

Please share your experience here.

Thank you.

I have a hole drilled into the water return right at the water line. This way there is no back siphon from the tank in event of a power failure.

Doesn't that cause a constant slight water leak? of course leaking into the tank and maybe an inch under water but am I understanding that correctly?

One way check valve

Yep, I have a small stream of water that comes out but it's a small price to pay for the safety. As mentioned you can also use a check valve. I went the cheap option. LOL And if you drill it downwards towards the water line you dont get splash up.

Thats the same with me. A 1/16" hole drilled about 1" above the water line. It loses very little, and actually sounds like a miniature fountain. Kinda soothing, but with no salt creep issues.

Whats a one way check valve? I'm going to lowes tonight to ask; sounds like the way I'd wanna go.

Thanks for your fast responses!
