My rear filter compartments in my Biocube29 have a growth that look like pieces of rice and attach to the walls and glass. I use to have a CPR3 skimmer and a lot of this growth was on the inside of the skimmer body. I can scrape it off and siphon it out but was wondering if anyone knows what it is. It shows up as yellow in the photo due to the flashlight. The organism is actually white or opaque in color.
