I've seen posts on Vibrant but I used Dr. Tim's Refresh and Waste Away. After 10 days it was like a new tank. I raised my Alk slowly to 11.5 and my coral growth noticeably accelerated. Everybody seems happier including 2 goni's that I nearly gave up on. I also had hundreds of mini tube worms that I just noticed today all disappeared! No trace.
I still get some brown algae on the sand during light hours so I continue to dose every now and then to see if it will eventually go away. I don't think it's worrisome though.
