How can I effectively remove and prevent the growth of black algae in my aquarium?

Getting rid of black algae in your aquarium takes a few steps. First, scrub off the algae and clean any decorations it’s growing on. Then, make sure your water stays clean with good filtration and regular water changes. Cutting back on light can also help since algae love too much light. You might also consider adding algae-eating fish or snails to help keep it from coming back.
