Sump overflow/power failure?

[jazzmik]

If I'm correct on the dimensions for the RS 450, if your return nozzles are 1" below the surface, you'll be draining a little over 5 gallons in to the sump until the siphon breaks. If they can be raised to just below the water line, it will cut that down a lot. A side benefit is surface agitation too.

As you likely know, there are many ways to skin the proverbial cat in this hobby. The siphon hole in the return line is one way as suggested. The check valve is another. In my opinion, I do not want to rely on either of those options. Not saying they won't work, but less failure points are better, at least in my mind. I'm not trying to start a debate here, and as I said, both may work. But both of those options will require some maintenance along the way to keep them clean. Just my $.02.

This was exactly the problem. I must have lowered them some.

Came home and had a bucket ready to bail water just in case... no need. Raised the nozzles to just under water level and perfect!

Thanks again for all the replies and suggestions!!

Love it when a plan comes together!!! Happy Reefing.

Love your manifold can you show me the whole picture of the manifold?

Let me see if I can make sense here...

Red Sea Reefer 450 with custom manifold, 3 gate valves for 2 reactors and uv sterilizer. Here's an old pic of when I was first setting up:

The question/problem:

Until recently I wasn't using the reactors so all 3 valves were closed. Water level in the return section is kept around 6-7 inches (the left return section baffle is roughly 9 inches).

This worked perfectly when doing water changes... turn the main pump off and sump would fill up to around 3 inches or so below top of sump rim. Been doing this for most of year no issues.

Now... all 3 valves opened and in use, turn the main pump off and sump filled complete to rim and would have kept going if I didn't get pump running again real quick.

How can water still be filling the sump with the pump off? Water still flowing through the UV/reactors.

If I close all 3 valves first, turn main pump off, no issues. Now has me worried about a power failure if I'm not home.

Advice?
