RemoPhos AL 1-3mm - phosphate adsorber based on aluminum RemoPhos Al quickly and safely removes large amounts of phosphate, silicate, humic acids, organic pollutants and dyes, as well as unwanted trace elements (arsenic, barium) and phosphorus compounds from your aquarium. No harmful substances are released. The pollutants are firmly bound to the surface of the adsorber and are not released again. In this way, the nutrient content of the aquarium can be kept very low and the water always clear, and unwanted algae growth can be effectively prevented. RemoPhos Al is very effective and was developed for use in nutrient-rich tanks. Therefore, it should not be used with low phosphate levels (below 0.03 mg/l) or undetectable nitrate levels. Application: Rinse RemoPhos Al briefly before use. Start with a maximum of 25g RemoPhos Al per 100l of water. After two weeks you can increase to a maximum of 500g per 100l of water. This dosage should never be exceeded! The phosphate concentration should be checked regularly during use. If the phosphate value increases, the adsober should be replaced. RemoPhos Al should be used in a filter or filter chamber with a relatively moderate flow rate. To achieve the optimal effect, an upstream particle and activated carbon filter is recommended. RemoPhos Al should not be used in the fluidized bed filter, as the swirling around could cause the accumulated phosphate and components of the adsober to be rubbed off and released again. At extremely high nutrient levels, it may take some time until a measurable phosphate reduction is achieved because phosphorus compounds are bound first. The water initially becomes significantly clearer. There is also a slight yellow discoloration of the adsober. RemoPhos Al can heat up when it comes into contact with water.
