Aquarium Advice Regular
I have a Aqua-C Urchin Pro and twice this has happened, Not changing any of the skimmer parameters, it seems that everything is fine, producing sludge in the cup for months, then every once in a while I notice the sump surface water is bubbly like the Ocean, and the bubbles are rising much more rapidly into the cup and overflowing the cup with clear water??? Any clue why this might be happening??? Has this ever happened to anyone else??
