Algae help please what is it ? Need advice.

[reefdude101]

Is this some kind of algae that does well in a low nutrient environment ?

Has anyone got an ID on this algae or seen it before it doesn’t look like GHA, I cant see much GHA at all except for the bit on power head/tiny bit on snail shell it’s all this brown algae, tank is over two years established/mature might be diatom not sure but doesn’t look like Dino either.

It’s not out of control but I can see it getting thicker in spots/multiplying on overflow box/power heads & some rock when as far as I can tell via testing it shouldn’t be.

Any ideas/input ?
Running out of ideas to get this under control before it becomes a problem really bumming me out as tanks been doing great.

It looks like GHA. Green hair algae.

Sometimes you can read low phosphates and nitrates because the GHA sucks it up too fast. Get a thin hose and when you do waster changes suck it out. That will help control the growth but you will need to find the cause and correct it.
