hydrogen peroxide and dinoflagellates

[bigj_51]

I dosed 1ml per 10 gal and went lights off and tank covered for 3 days. They came back. So I hit it again with h2o2 and went lights out for 7 days. I lost 2 small zoo colonies but they haven't come back since. I kept dosing for about 2 weeks after as well. Everything else seems fine. I stopped feeding blood worms and swapped, my fuge light out to grow macro better.
