Brown Algae on Small Leaves
I've been having brown algae grow in my tank at a fairly slow rate for a while now. I've mostly addressed it by scrubbing patches of it off of my leaves/ glass as they arise.
The biggest issue I have encountered is with my small-leaved plants (such as s. repens). It's difficult to scrub these leaves without damaging them.
Does anyone have any advice about how to treat this?
