Hi all, I’ve been dealing with this hair algae for almost 2 months now and I can’t get rid of it. I have two sea urchins and multiple snails that don’t seem to help. I’ve done many water changes and I’m dosing a redsea algae supplement. I don’t know what the cause is because I already have low nutrients, phophates at around 0 and nitrate at 5. If anyone could help, it’d be much appreciated.
