I've got a 25 litre tank with a single male betta in. It's a gravel and silk plant tank (I would like to switch to a full planted one day but that's another story!) and I just can't seem to stop the growth of the brown/black algae on the plants and the big chunks of green algae in the gravel and on the tank sides. His light is on for about 10 hours a day.
I don't really fancy going down the chemical route, so does anyone have any advice for something that would make this more manageable?! A snail? Pleco?
Thank you in advance, if I can slow the growth of this stuff down, it would really help!
