I have been battling GHA for the past year in my 25 gallon Nano. Eight months ago, I dosed 2X recommended dosage of Reefflux and it worked like a magic. All of the GHA turned white and died within a week, and I saw no side effect on my LPS and chaeto. I did not do water change for four weeks to make sure that all of them are gone.
Two months ago, the GHA came back again. I dosed 2X the dosage again, but this time nothing happened for two weeks and I start to see less polyp extension on my torches. So I made a water change and left the GHA alone for a month. I dosed 4X the dosage four weeks ago, and to this day, I still see no effect on the GHA. They are actually growing crazy in my tank.
I did manual removal and I have a refugium for Chaeto. My phosphorus is already at 4ppb and my light schedule are only for 8 hours with almost only blue channel. I have added a purple sea urchin and it did not help much. I only have two nano tanks, so having a tang is not really an option for me.
Any idea what has gone wrong this time, and any suggestions? I am hesitant to further increase the dosage.
