I have a Red Sea Reefer 200 G2 with a Reef Mat.
I've had stable settings on the down flow valve and the return pump for a couple months. I haven't changed anything.
All of a sudden this evening, the water level rose and there was high flow down the overflow pipe in addition to gurgling into the Reef Mat on an almost clockwork basis. Just gurgles every 10-20 seconds or so. My ATO alarmed for water being too high in the return part of the sump. I have a normal return pump and I also have a pump that is running my hang on UV sterilizer.
Thoughts on causes? I cannot get it back to how it was just 1 hour ago. The gurgling is going to drive me batty but more importantly (perhaps) is that the return part of the sump is just having water dumped into and it flows over and not through the black sponge.
