Need help identifying this alage

Hi everyone I'm on whit ends with this setup after the reboot. I've been battling this algae for a couple months now but can't seem to find out what it is. At first I thought it was GHA but it turned white and has bubbles in it. I would manually remove it and will come back my numbers

Looks like calothrix which is a member of cyano family. Take rock out and scrub in a bucket of tank water and return to tank
Add cleaners afterwards such as astrea and nerite snails, emerald crabs, chiton snails and even pin cushion urchin
