I have a freshwater aquarium 4feet with a few Discuss and few cleaning fishes . I havea few plants .I started adding liquid fertilizer recently and the plantsstarted looking more healthier but suddenly I have noticed a lot of algae growth (black hair like algae) I don't know the exact name. So I have stopped fertilizer.
My substrate is river sand which is sold locally in India from some riverbed. I recently also changed my lighting to Led
DIY . No CO2
yet waiting for the cylinder.
