Return not working

[garyisrael]

Last night I had a power outage and now my return pump is working but return water back to sump is minimal causing overflow of the main display tank. I’ve tried slowing the flow but nothing seems to work. Any ideas?

Does the tank have a gate value on the drain to the sump? If so open it all the way up. If not maybe something is stuck in the drain line?

I have ball valves. It’s a 180 with dual corner supply and returns. I’m thinking maybe sponge is clogging up the works. Every time I shut down the pump to do a water change when I turn it back on tons of sponge pieces blow out.

Built in or external overflow

What kind of stand pipe are you running. If it’s a Dorso would check that the little breather holes at the top are not clogged with salt.

Thanks. Did that. I’m at the point now that I’m thinking about hooking up my shop vac to the return pipe at the sump and pulling then blowing to see if anything pops loose…

Pick up a CPAP hose cleaning brush on a long wire.

You should be able to feed it all the way from your overflow drain to the sump.

Yes I had the same thing happen when I slowed the flow back to the sump by blocking it with a sponge. Check for a blokage
