Ok quick questiom Halamedia

Ok i have a 55g tank with PC lighting (yes i know it is outdated, shopping for another 24" 24wx4 t5 ho fixture, so i can put one on each side). I have about 75lbs of live rock, and about 50-60lbs of sand / crushed coral. The crush coral is only about 1"thick and is the base for the sandbed....

Got some coral on rock with hair algea all over

I picked up some zooanthids, xenea, leathers, candy canes. Anyways, the rocks that these are on are covered in green hair algae. I fear putting them in my 99.99% algae free tank. I don’t want this algae to spread to everything in the tank obviously. I keep my nitrates and phosphates down which is why...
