Hair algae removal HELP

[saltyair]

A few questions first :-)

how old is your tank? what type of lighting? have you tested for PO4 and NO3?
how long are your lights on?
what is the bio load?

Simple answer yes a sea hair will eat GHA. I would suggest renting one not purchasing. this would be a quick fix.

A few helpful tips to get GHA under control

#1 use ro water
#2 weekly or bi weekly WC
#3 using carbon and GFO
#4 refugiums help a ton once established
#5 if using T5's they should be changed out every 9 to 10 months.
