Right now I am dosing 50 ml of Vibrant twice a week. I have never had any issues with Vibrant as some may have. I do feel if effects LPS more that SPS, IME. I just ordered 2lts of Microfactor7 and will dose it at the same time. I already lost 4 SPS frags that were testers, but, were doing good until this outbreak. I can't add anymore corals to the tank until I get this taken care of. I hate looking at a bare tank. I love my fish, but want corals in the tank as well.You are far more daring than me, I didn't have a great experience with vibrant. The only bacteria-based product I dose is 6 drops of zeobak once a week, I used it through dinos, then cyano, and just lowered the dosage to once a week. Not sure what it does for me now if anything.......
This is an aggressive, but, not a reckless or short cut approach.
