Hair-like Green Algae, beneficial or harmful? Options

[CyberET]

monitor parameters from water change, till brown algae appear, may show a clue to what is the prob.

the only time i experience brown algae is when i don't change water for a few months, only 5% topup a day due to evaporation.

seems like kois don't like to eat brown algae too

The presence of brown algae is just an indicator of something is amiss very much like a thermometer telling you that you have a fever but it does not tell you exactly what's wrong.So for a start,like ET pointed,the parameters have to be addressed........That's the basic.Of all the algae(Green,brown,blue-green)you may encounter,only green is acceptable.The green is another very realiable indicator that everything is in GOOD order...

I have both green and brown in my tank.

But 90% are green.
