Fussy hair algae rocks

[Nanoreefer1999]

My tank is small 13.5 gal fluval evo. Not any mods. Just put phosphate remover some carbon and the reg bio filter. Just did water change trued scrubbing off the algae from rocks. But rocks still look fuzzy. Perimeters look fine for the most part. Clownfish doin great! Just wish the rocks did not look fuzzy

You're always going to have some kind of algae on rocks that don't have corals grwoing on them. I'd suggest some hermit crabs or small tuxedo or royal urchin.

What kind of urchin will do best and not affect the bio load from the fish. I have 2 clowns, a black bleny, and pistol/goby pair that barely comes out of their cave.

Tuxedo urchin are recommended for GHA. Just know they also eat coralline algae
