SVS Aqua No-Phos phosphate-free treatment solution

No-Phos® PHOSPHATE REMOVER FOR SWIMMING POOL WATER TREATMENT

WHAT IS No-Phos®?

NoPhos® is a natural phosphate remover designed for swimming pool water treatment. Phosphates enter pools from water supply, debris, or bathers, and act as a fertilizer for algae and bacteria. By eliminating phosphates, NoPhos® starves algae and harmful microorganisms, resulting in clean, crystal-clear water. 

Safe and effective, NoPhos® can be used in: 

  • Public and private swimming pools
  • Natural swimming ponds
  • Decorative water features and fountains
  • Aquaria 

KEY BENEFITS OF No-Phos®

  • Eliminates phosphates – Prevents algae and bacteria growth
  • Safe & natural – Suitable for pools, ponds, and aquaria
  • Improves filtration – Works as a coagulant with AFM® or sand filters
  • Crystal clear water – Enhances pool clarity and water quality

How to use NoPhos® FOR POOL WATER TREATMENT

Only a small amount of NoPhos® is required: 

  • 10 ml of NoPhos® removes 1 g of phosphate
  • Example: A 100 m³ pool with 0.5 ppm phosphate contains 50 g phosphate → needs 500 ml NoPhos® 

Dosage Guidelines: 

  • Public Pools – Do continuously use a peristaltic pump before the filter. Dilute 1 L NoPhos® to 20 L of water and feed 1 ml/m³ circulation.
  • Private Pools – Add manually once per week at 1 ml/m³. For an 80 m³ pool → add 80 ml weekly.
  • Natural Pools & Ponds – Dilute 1:20 and dose continuously with a dosing pump. Keep phosphate levels slightly above zero for biofilter health.
  • Fountains & Water Features – Use NoPhos® with or without filtration to control algae and bacteria growth.

PRACTICAL USES

In a Public Swimming pools

In a public swimming pool, phosphate is measured weekly. NoPhos® is automatically and continuously added to the pool using a peristaltic dosing pump. 1 litre of NoPhos® can be diluted to 20 litres using clean water. This solution is then continuously dosed into a ZPM® before the filter at 1 ml per m3 of water circulated. Example: 100 m3/h circulation = 100 ml/h of diluted NoPhos®. Depending on the weekly reading, the dosage will be adjusted up or down.

In a Pond or Natural Pool

In a pond or natural pool NoPhos® is the ideal product. It works best when diluted with water to a ratio of 1:20 and then continuously dosed with a dosing pump into a ZPM® before an AFM® filter. Some phosphate should be left in solution to help maintain the biofilter performance, so occasional measurement of the phosphate concentration using a precision photometer is important.

In a private swimming pool

In a private swimming pool Nophos® is used prophylactically and is added to the pool manually once per week. The dosage used is 1 ml of undiluted NoPhos® per m3 of pool volume per week. For example, if the pool is 80 m3, add 80 ml of NoPhos® every week. We recommend it is added into the skimmer or to the overflow channel. If NoPhos® is added directly to the pool, there will be a short period of higher turbidity. Precipitation is normal, and shows that the product is working. If a heavy grey precipitation is observed on the pool bottom a little too much NoPhos® has been added, future dosage should be adjusted accordingly.

In a Water Feature or Fountain

In a water feature or fountain NoPhos® and ACO are suitable to keep the water clean and clear and to help prevent algae and bacterial growth. Both products will work even with poor or no filtration. NoPhos® reduces bacterial growth but is not a disinfectant. To provide higher protection against Legionella, our DryOx chlorine dioxide tablets should be considered.
