Instructions
Reduce light in the tank by keeping lights on less than nine hours a day.
Stock tanks with fish and other creatures that consume algae, such as mollies, otocinclus and hermit crabs.
Swap out the water in the tank every two to three weeks. Vacuum the rocks and debris in the bottom of the tank. If the tank is saltwater, clean with distilled water.
Replace filter pads every week. Older filter pads get clogged and cannot keep tanks as clean and often dump nutrients that feed algae back into the tank.
Scrub aquarium walls with an algae magnet. Algae magnets are a two-part scrub brush. The brush or scouring pad, which goes inside the tank, has a magnet that allows the user to guide the brush with another magnet, so that the user does not need to reach into the tank.
How to Eliminate Algae in a Marine Aquarium
Algae grows where light and phosphates are present, and in marine aquariums, both are plentiful, making algae growth inevitable. If algae growth persists, it consumes the nutrients fish and plants need to survive, making removal necessary. While chemical removal can harm fish and plant life in an aquarium, there are methods of regular upkeep, stocking the aquarium with specific fish and adjusting tank settings to clean and reduce the appearance of algae in aquariums.
