During the holidays, almost every year, my tanks take a hit as I skip a wc here AND there. I started using Vibrant on both my FW and SW tanks. Vibrant for FW took care of the algae in my FW tanks w/in a few weeks, I'm down to 1mL per 10 gallons every two weeks in the FW tanks, have to say, Vibrant works for my tanks. However, in my reef, byropsis and bubble algae got way out of hand on both the rock and on the sand bed. I raised my Mg, which took care of the rock byropsis, but it didn't touch what I thought was byropsis on my sand bed. I started Vibrant for reef tanks on 3/11, dosing 1mL per 10 gallons 2x a week, the bubble algae is slowly fading, but my sandbed is still a mess. During a wc a few weeks ago on my reef tank, I noticed the sand bed algae might be some sort of hair algae, hence, the interest in this fluconazole treatment for hair algae. I ordered some capsules of fluconazole, it should be here tomorrow. I'm going to dose 7.5 capsules (80 gallon water volume) and see what happens (would someone check my math please). I'll post results here.
