ARKA Phos Out 4 - 473 ml

Lowers phosphate quickly - ARKA Phos-Out 4 removes excess phosphate from the water of freshwater and marine aquariums and helps keep water values stable. This deprives algae of a key nutrient. Polymer-based phosphate binder - The formula contains no heavy metals and binds organic and inorganic phosphates without affecting the biology. It lowers phosphate in a controlled way. Dose in small steps - Add max. 4 ml per 100 litres in freshwater and max. 2 ml per 100 litres in saltwater every 12-24 hours until the desired PO4 level is reached. Shake well before use. Keep an eye on phosphate - The target value in marine aquariums is 0.02-0.05 mg/l phosphate, and a PO4 deficiency should be avoided. Break down phosphate sources in the substrate with ARKA Substrate Cleaner. Generous 473 ml bottle - The 473 ml bottle is suitable for medium to large aquariums and regular use. Dose into an area with strong water flow, not directly over the animals. For aquarium use only.
