just curious what your take is on micro algae, the green kind that likes to spread fast and go on the glass of my aqaurium. I've got the green kind. that tends to glow long hairs. is there any benefits to keeping some on my back wall and just letting it grow on its own? I bumped my lights up to 12 hrs on and off and that seems to be spreading the growth really fast. I had it at 10 before, and it was fairly under control. Also my rocks are stacked so that cleaning all of the back wall would be a bit of a pain. So, I was debating on just letting the back wall grow. But not sure if this will help out my tank or make it worse. What's your take?
