ARKA Phos Out 4 - 236 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. Practical 236 ml bottle - The 236 ml bottle is suitable for small to medium-sized aquariums. Dose into an area with strong water flow, not directly over the animals. For aquarium use only.
