Algae keeps coming back

[geosReef]

I clean up my sand and rocks every week for the past month and hair algae keeps coming back algae on stops slowed down but on my sand is crazy. I have crabs snails sea hares and tang but nothing seems to help. How do you guys deal with it only 10 month old tank

We would recommend increasing flow, weekly water changes, and make sure your phosphate levels are not high by checking with a Hana ULR water tester. If you are having phosphate issues add GFO to the tank and starve the algae out.
