Aquarium water cleaner Algan

Against red and black nuisance algae in saltwater aquariums: There are various reasons why nuisance algae appear in aquariums. This type of coloured bacteria can multiply freely if the concentration of nitrates or phosphates is too high, if the water movement is insufficient, if the substrate layer is too thick, if the lighting is altered or unsuitable, if there are spores in the tap water, or if, on the contrary, the water is "too pure." In "sterilised" seawater, these algae can spread just as freely as in heavily polluted water. With Preis-Algan, you'll quickly have clean aquarium water again. After the Algan treatment, make sure to tackle the causes of this pollution.
