Thankfully the flux hasn’t hurt my chaeto yet. Growing like crazy!!! I’m sure from dieoff. One of my acros just started bleaching a bit today☹ bummer. Thinking about throwing in some carbon and getting a water change ready. Just so frustrated with this stuff. If I knew for sure it was just gha will definitely go a different route as my Bryopsis is not a bad matter yet, almost gone from the flux now too. Tough choice cus I’m already in it 5 days but if I already have 1 going…. May have to pull the plug on the flux.The light green stuff looks like gha, my Tangs didn’t like the stuff. The Dark Green looks like Byropsis, my Tangs will eat that, and keep it under control. The gha will grow over Byropsis, and smother it. I purchased Fluconazole, fellow Reefer Suggestion Vodka Dosing instead for the gha, since the Fluconazole, would kill off my desirable Macros. The Vodka is working great, I’m on my 70th day, and I’m up to 5.0ml per day, on my gradual increase.
