I've started dosing my tank every day with 10cc H2O2 (75G DT & ~25G sump/refugium) and am on day 2. I decided to treat in tank as the rocks are HEAVY and I've done some gluing/puttying that I don't want to come undone. Gonna try this for 8 days and see how it looks. Wonder if I should do a couple water changes within the 8 days? If I need to after that I'm going to raise my Mag as I have some bryopsis (sp?) which I've been trying to carefully pluck. I also got a lawnmower blenny...and man that fish is going to town!
