Phosphates and alage

Can gha and cyano starve itself by using up most if not all phosphates

[Mhay]

I don't know about hair but we just went through a spat with cyno in our 29BC and it got way worse before it got better. Tried just about everything except for chemical means. We decided to just let it be and it started to get better. The cyano was there a solid 8 weeks before it started to get better. Less than a week ago we added a a GFO reactor and it zapped it gone. So from my experience I'd yes it's possible but just know it's going to get nasty first

Not if you continue to provide phosphates. Otherwise, it will continue to grow / live in your tank.

Ways that you can reduce phosphates:

-don't overfeed
-having 0 TDS RODI water
-using completely dead rock that is free and clear of phosphates (acid bath)...and/or using live rock that is phosphate free

Hair algeas growth will be limited by reduced phosphate levels but cyano most likely will not it will still thrive regardless if your tank is fairly newly setup maturity will eventually rid u of cyano in most cases
