Algae are an integral part of aquariums. Even though they are not visible at first glance, they belong in every tank. Algae are not only a nuisance, they are also part of the natural ecosystem, just like other microorganisms. Deposits on the glass should nevertheless be removed at least twice a week. Even though snails and certain fish species such as catfish keep the glass clean in a natural way, aquarium glass cleaners are part of the basic equipment. These are available in many models to meet the different needs of the underwater landscape as well as the requirements of aquarists. Among other things, glass cleaners with steel blades, cleaning gloves, algae magnets as well as floor cleaners and vacuum cleaners that reliably remove dirt are available. Multi-functional sets are among the most practical aquarium glass cleaners, as they offer quick and comprehensive cleaning.
