Heat/return malfunction suggestions on inverts for the refugium? My return pump didn't run for about 24 hours, the thermostat is in the display and heater in the sump. You can guess the rest. Cooked the fuge I see a lot of dead apopods. Lost the few hermits I had in there pulled the chaeto it's soft and didn't feel healthy. I don't want to suck the miracle mud. Ok real question is what to put in the fuge to take care of the dead pods? Just a few hermits or do you all suggest something else, it's a small fuge I'd say 3 gallons or so. If you look closely at the pic of the substrate you can see dead pods. The pictures have the light on, I run the light at night. I plan on replacing macroalgae and pods.
