Hi all!
I have an AquaMaxx HOB refugium on a Waterbox AIO 50.3 (4 months old) - no chaeto, more of an algae scrubber at this point. When I do maintenance these white semisolid foamy/sponge like items are found in the algae or located solo. Most are all white, with some having a yellow/rust/brown stain like in the photo. I occasionally find pineapple sponge in the tank, and these refugium items don't resemble them. Largest one was almost 2 inches. No foul odors, refugium flow not vigorous but circulating, algae grows thick and green. Is this a sponge? Congealed proteins and fats? Thanks!
