Film/green hair algae and maybe bacteria (pics included)

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?

Can you post your parameters? S.G, dkh, ca, po4, no3

Do you have a clean up crew?

My fix for growth on the rocks....

Every 3 days just a few hours before a filter sock changed I take a tooth brush and spend 5 minutes cleaning off 1/2 the tank rocks (so both halves get done once per week). Run the circ pumps wide open for a few hours to get as much into the socks as possible.

Problem solved

S.G. 1.025
dKh 11
Ca 430
po4 and no3 are undetectable right now using red sea test kit (obviously it's there though).

I do have a clean up crew of blue and scarlet hermits, and nerite and trochus snails.
