We have been adding 20ml of live Phyto to our tank everyday for 6 weeks. While everything looks real happy, I have noticed that most of the Coralline algae has disappeared. It has been replaced with a bit of brown algae. Its not a bloom, just a slight accumulation. My guess is that the live Phyto is out competing the Coralline and at 20ml per day, we are adding more than is consumed. I think I am going to cut our dose of live phyto in half. We don't have gha anymore, which is a positive. The other thing I noticed it that the brown algae seems to be growing better in the frag tank than the DT, even though they are plumbed together.
Cheers!
