This yellowish/green algae keeps coming back! Tank is about 3 years old. In the past, I've done a blackout for 3 or 4 days, and it would cease. But this year so far (2023) I've had to do blackouts of 5-6 days, with blackout curtains covering, 5 times now. And each time, within 2 weeks, it creeps right back in.
In my tank:
- 2 starfish
- 7 anenomes
- Yellow wrasse
- 2 clowns
- Dwarf Fire angel
- Royal Gramma
- Blue/Yellow Damsel
- About 8 Hermits
Tank size:
- Red Sea Reefer 350 - 100 gallon
- Sump has small refugium / light, no specific additions. Used to do Red Ogo tumbling, stopped that after a tank move threw it all over sump/pumps...
Current Parameters:
- Salinity: 1.026
- ph: 8
- dKh: 0.1 (Hanna Alkalinity Test)
