green hair algae

[Porkenchop]

whats the best level of phosphate to have to stop the growth of gha

 

[SPR1968]

Zero phosphate, but if you have GHA already it’s probably using it as a food source and giving a false reading

You will need to look into phosphate removal methods, personally I use rowaphos

You can try tangs or sea hares to help cut back on the algae, manual removal works as well or some turbo snails, ideally 0 phosphates

I have a Foxface rabbitfish. I also got some gold ring cowries, they destroyed the hair algae.

I once read a post by someone who had great success using Vibrant to get rid of GHA. It is reef safe, too.
