I was following a thread on vitamin c dosing for zoas that wouldn't open. The Vitamin C I used also contained magnesium stearate. My tank is all softies, including a basketball sized sebae anemone. After 2 weeks of dosing 500 mg tablet vit C (walgreens) once in the morning and once at night, all of my algae is gone. (100 gal tank) I don't kinow if it was hair algae, or bryopsis. It was every where for a very long time, even bubble algae is turning clear and fading away. All occupants in the tank seem fine, including anemone, zoas are starting to open, 3 rocks of hairy mushrooms, all different kinds, one rock is bleaching, all others are growing bigger and more colorful. Mag level is 1600,
I have no idea what it was before, my calcium has gone up to normal levels, my ph has remained the same at 8.1, alk went up slightly to 4.5, dkh 12.8 , but the algae died just as people are describing here. Chaeto looks good yet.
