Algae identification

[yekutiel]

Hello everyone
I have a major algae outbreak
At first they were in a few places and after I scratched them with a toothbrush they spread everywhere
I have 0.00 phosphate and it could be because these algae are eating all the phosphate
I supplement the aquarium with amino acids and also trace elements and eat Fauna Marine corals
My tang doesn't touch the algae, nor does a hedgehog eat them and neither do the snails

Would appreciate help

It looks like green hair algae (GHA) to me. Snails and some fish seem to prefer it only if it is very shortly cropped down on the rocks. Your phosphates are probably reading zero in the water column because the algae is using it all up for growth.

This will take some good elbow grease and scrubbing on the rocks with brush to break it off. Then, looking closely at your nutrient levels. If this is a new tank, it is going to go through several different ugly phases.
