Green Hair Algae - Will not go away!

[reefwars]

if your scrubbing the rocks in the tank thats a bad idea , try pulling out as much as you can manually then target drop turbo snails on there when they leave the patch pick them up and drop it on them again. boiling water helps too.

sea hares work they are just fragile and need to be accimated very very slowly but one should clean your tank out in no time, any ideas why he died??

how long have you been v/ dosing???

Do you have any direct sunlight can reach the tank at all? That could promo hair algea growth.

I used to have the similar problem until some guy told me to move all coral to a QT tank and keep the main tank running without any light for 3 months, I end up solved the issue that way. However, you will have a big enough QT tank and also have te time to keep up the water quality in the QT tank.
