Is this green hair algae? I've had issues with turbo snails and emerald crab dying when eating this. All my other snails that don't touch this algae are perfectly fine, but this one seems to kill them. I've lost one urchin, the pincushion seems fine and the larger tuxedo. But it was looking rough for the tuxedo until I took all the rock out and hydrogen peroxide bath them. This is no longer growing on the rocks I soaked, but it's still on the sand and random parts of the tank.

Tank is ~1 year old. Ups and downs in it. I cleaned a lot yesterday so I don't have the stringy pics of the algae anymore.

Parameters seem fine. PO4 .03, NO3 5, magnesium 1180 ( a little low), calcium 450, ph 8.0, ammonia 0, nitrite 0. I've been dosing macrobacter7 daily.
