surface algae
Hi
I have a problem at the moment with water surface algae (it is a thin green mist on the water surface like a green oil slick very very thin and light green and transparent)
the air pump brakes it up over night when the lights go off but it slowly comes back during the day after 7hrs of light.
how do I get rid of it ??
