Question for yall. I have a FOWLR
aquarium, with only 2 small fish and 30lbs of Figi rock.
I had a Fluval 404 and a Reef Octopus HOB
skimmer. All was well until i broke the 404 and had to replace it. I replaced it with a Rena XP3. Once i turned the XP3 on, my skimmer went crazy and the cup filled with foam/water. It has been a week and the foam level has gone down but nor to where it was before i replaced the 404. And now it is really only skimming murky water.
