I've had this modified bio cube 29 running for about a year now and have gone through various algae battles. For the last few months however I've had this very slow, slimy, green and brown growth on my rocks. It's getting so bad that it's clogging up the filter floss on my overflow in a few hours (10-12hrs). I have an algae scrubber that's been running for two months with basically no growth... I have an AI prime set near 18-20k for 10 hours a day. Do 10% water changes weekly. Use a small protein skimmer. I have no detectable phosphate or nitrate. Run carbon. Use marine pure spheres. ID on the growth? Recommendations?
