Hose dispenser with phosphate binder tablets for refilling water or for integration into a filter circuit.
Phosphates can enter pond water in many ways. Tap water is often already enriched with phosphates, so topping up the pond to compensate for evaporation or after vacuuming can lead to renewed algae growth. Phosphate adsorbent materials, such as Phosgran, require a certain residence time or a low flow rate to be effective. These materials are therefore better suited as long-term filters.

The American company Applied Polymer Systems Inc. has developed a phosphate binder that requires water flow to be effective. It is therefore ideally suited for treating top-up water. Our own tests have shown that the phosphate binder tablets require a reaction time. A slight phosphate drop of approximately 10% can be measured immediately after application. After one day, the phosphate level of the added water was below the photometer's detection limit (0.01 mg/l). It should be noted that this was under laboratory conditions. APS states an average reduction of between 75-85%, which seems realistic to us as an average value in real-world conditions. However, in real-world conditions, external influences cannot be precisely controlled. Therefore, results may vary. Our own test in the pond resulted in a significant reduction in the phosphate level.

The tablets have a rubbery consistency. The polymers dissolve in the water stream and bind the phosphate molecules in a flocculation reaction. After use, the tablets can be dried and stored until they are used up. The hose dispenser has two click-fit connections for garden hoses and can withstand a water pressure of up to 8 bar. Refillable with replacement tablets.

Scope of delivery: Gardena hose dispenser with click connector for garden hose. Includes one filling of phosphate binder tablets.
