Stringy Algae - can’t get control of

[mtnrunner]

I have a 90 gal sps/fish tank that I’ve been fighting this stringy brown algae for a couple of months. I have 4 MP40s, 2 Radion lights and Parms are below.

Alk 9.5
Ca 429
Temp 78
Phos 0.01
Weekly water change of 12 gal
Skimmer

I’ve treated with ChemiClean twice and it isn’t helping.

Any suggestions and help appreciated.

Looks like dinos to me. Ime, I did hydrogen peroxide and mb7 for about a week and it helped. I also got my nitrates up to 20ppm and my phosphates up to .10ppm.

How much hydrogen peroxide to dose/gal? What is mb7?
