So that the aquarium inhabitants always feel comfortable, the water must be clean and above all free of pollutants. For this reason, in addition to an efficient, reliable filter, a water conditioner is absolutely necessary in addition to regular partial water changes. Since aquarium inhabitants have individual demands on their habitat, there is no ideal aquarium water, but the tap water used must be adapted to the needs of animals and plants. Since tap water for fish and invertebrates can contain toxic lead, copper and zinc, these substances must be quickly removed from the water using a water conditioner.

Everything for animals: Aquariums Water conditioner Video Guide

Water conditioners, such as the product Sera Aquatan, transform tap water into aquarium water suitable for animals and plants. Ingredients harmful to fish, invertebrates and plants are neutralised immediately. Heavy metals are bound by the complexing agents contained in the water conditioner. Water conditioners also eliminate chloramine and chlorine and enrich the tap water with vital ingredients present in the natural biotopes of aquarium inhabitants. Magnesium is needed by fish for growth and optimal well-being. Biocolloids promote the formation of bacteria, which always keep the water in the aquarium crystal clear, iodine is used for vitalization.













The pH value of the water in the aquarium can be determined with the help of water tests (rods, droplet test). Since the different fish species and invertebrates have different demands on the pH value, the aquarium water must be treated accordingly. While some fish and plants feel comfortable in soft water, other aquarium inhabitants prefer hard water. Tap water tends to be hard water, which should be softened for most fish. This is particularly recommended if fish species are to spawn in the aquarium. It is important to obtain information on the optimum water hardness before inserting fish. The water hardness can be adjusted using a water conditioner such as the JBL Biotopol product or an ion exchanger.

Over time, sooner or later the nitrite (ammonia) content in the aquarium will increase. Reasons for this are the excrements of the animals kept in the aquarium. Nitrite damages the health of the animals. To regulate the nitrite content in the aquarium, well growing aquatic plants, weekly partial water changes and the use of a water conditioner are recommended. However, regular partial water changes alone do not guarantee optimal water values for the residents.

Water conditioners are offered by various manufacturers such as Dennerle, Tetra, Sera, Easy Life and JBL. As the exact composition of the water hardener cannot be determined for most products, a meaningful comparison between the different products is not possible. In order to determine the price-performance ratio, the dosage recommended by the manufacturer must be used.

Special water conditioners, such as Dennerle Nano Water Care, are offered especially for nano aquariums. This water conditioner binds pollutants to which invertebrates (shrimps, snails, dwarf river crayfish) in particular react very sensitively and immediately enrich the aquarium water with natural care substances and biological active substances. Since water conditioners can lose their effectiveness when stored for a long time, water conditioners for nanoaquariums are offered in small bottles that are consumed within four to five months. Water heaters can be tested for their effectiveness. For this purpose, twice the amount of potassium permanganate recommended by the product manufacturer is put into a separate water container and the water conditioner is dosed according to the manufacturer’s recommendation. The faster the purple red colour disappears, the more effective the water conditioner is and the faster chlorine is neutralised in the aquarium water.

– Water conditioners are harmless for the cultivated animals and plants – water conditioners neutralize chlorine – water conditioners bind copper and toxic heavy metals – water conditioners provide the sensitive mucous membranes of fish protection – water conditioners do not impair the effect of plant fertilizers
