Green hair algea

[Ghostyboythedog]

Hey, so I have a hair algea problem and we've tried everything the Toothbrush then siphoning it out, it hasn't worked, we also tried algea fix and didn't notice anything it's a 30 gallon tank, the tank mates in there are coral beauty, clown pair and yellow tail damsel we had a goby but it unfortunately passed away of old age, there are no corals or anemones. Open to any ideas to help get rid of it.

Nitrate and phosphate levels? What are you using for lighting? What is your water change schedule/amount?
