Algae Treatment with Scaleless Fish

[UnderwaterGamer]

Happy weekend everyone! Just wanted to get opinions on how to treat nuisance algae while a scaleless fish is in the tank. I’ve had this crap growing for ~3 months now and I can remove about 70% of it easily during my weekly water changes, however it keeps coming back non stop. I’ve tried Chemipure Blue and BRS GFO with no success. So, is there any algae fighting products (like Vibrant) that are safe for my Frogfish and will help contain this algae?
TIA!

I’m using vibrant currently but I’m not sure if it affects some fish more than others. I can say after one dose I noticed a difference in in my sand bed. Def whiter. As for gha start with pulling it out. Use an air line tube as a siphon and take little bites by pinching the tip of the tube and pulling it out. Let go and the algae goes up the tube. Try adding to the cuc as well, maybe an urchin (tuxedo).
Good luck.
