Green hair algae

[freddy]

I read about using a syringe of boiling water and squirt it into the algae,so I was doing a water change the other day and decided to try it.I didn't use a syringe but pulled a piece of rock out that had hair algae on it and scrubbed half of it with a toothbrush(in the water I had taken out) and the other half i poured boiling water on to,the half I scrubed,hair algae is growing back,the half I poured boiling water on is as clean as can be,no sighn of algae returning.Yellow tangs are very good at keeping it in check.
