Hello all,
Been battling GHA for the past 7 months.
I've tried everything I can but still can't beat this for some reason.
Tank is about 15 months old.
Things I have tried:
- Setup a refugium (GHA takes over and my dragons breath macro algae gets covered in GHA)
- Use Chemipure Elite (for the GFO)
- More CUCs (They seem to die after a week for unknown reasons)
- CUCs that died are Trochus, mexican turbos, hermits, astrae, strawberry conch, emerald crab
- CUCs that survive are cerith, dwarth cerith, tuxedo urchin
- Sea Hare (Died within a week)
- Normal dosage Reef Flux (3 week, no change)
- Normal dosage Flux RX (3 week, no change)
- Double dose Flux RX (3 week, no change)
- Protein skimmer (On constantly)
- Hydrogen peroxide dosing 3%, 1ml per 8g (No change)
- Hydrogen peroxide dip on rocks I can pull out when it covers the corals seem to help and knock it back on that specific area
- Weekly 20-30% water changes, manually pulling as much GHA off rocks as possible
- Copepods have all seemed to disappear as well, or at least very minimal signs of copepod life after dosing
Here is a link to my most recent ATI ICP test: //lab.atiaquaristik.com/share/3d33386a6eaf63620db7

Finally picked up a microscope today to hopefully get a positive ID on this algae. Here are the results:
100X
600x:
1200x:
I'd love to get more CUC to hopefully manage this, but they all seem to die a slow death after about a week.
I have a separate tank in my office which uses the same water mix and snails seem to all survive in there.
I've even tried moving the snails that were alive for months from my office tank to my display tank, and same result, after about a week, they all die.
Really hoping some experts can weigh in on this.
Thank you!
