I have this stubborn algae on my snails and Zoas only. The rocks look clean.
So far this is what I tried:
1. Use home made RO water and mix my own salt water with RedSea Salt. Change 4-5 gallons (50%) every week.
2. Currently dosing Vibrant and it has been one week since dosing fluconazole
3. Use a toothbrush to clean the rocks (not much debris came out)
4. Took the frag plugs (zoas and GSP only, not the frogspawn) and snails and dipped them in 3% Hydrogen Peroxide. This seems to have helped for a week but the stuff came back a month afterwords on the zoas. The snails were back to what they looked like within 2 days.
Tank details:
Age:
1.5 years old
Equipment:
Fluval Evo 13.5g
Filtration water flow: Filter floss > purigen > carbon >chemipure elite > Phosguard (removed carbon and purigen during the past week due to fluconazole treatment)
ATO from a 5 gal RO reserve
Lifestock:
2 x 2" clowns
1 x Cleaner Shrimp
4 x Astraeas
2 x Nassarius
2 x 1/4" Mexican Turbos
1 x Tennis ball sized Dragon Tongue macroalgae.
Corals:
4 x small Zoa colonies
1 x Frogspawn with three heads
1 x 2" x 2" GSP
Comments: All thee corals look extremely healthy. They seem to be extending fully every single day but I am not seeing significant growth at all.
Parameters:
Alk: 8
Phosphate: 0.2
Nitrate: 0
Nitrite: 0
pH: 8.2
I currently do not dose Alk since this is a softie only tank.
