Active oxygenating disinfectant (200 gr tablets) for disinfection of private pools 50 m³ to the pool volume. For larger pools  for economic reasons we recommend the use of liquid active oxygen (DEWAN-35).

Before Dosing:

Before using the DEWAN-20 disinfectant, do the disinfection of the entire water circuit of the pool! ("Shock")

Mix 0.5 kg / 10 m³ ALGA-SOKK P granules in the water, previously approx. Dissolved in 10 l of water. Swirl the water to mix the drug.
(a) If the free active chlorine content of the pool water drops below 1 mg / l within 24 hours, treatment should be repeated.

(b) If the free active chlorine content of the pool water exceeds 1 mg / l after 24 hours:
- We can wait until the free active chlorine concentration drops to zero (1-2 days)
- The free active chlorine content is reduced to zero by the addition of CLASS NULLA calculated on the basis of the measured free active chlorine content.

Starting dose:

Start water treatment 150 ml / 10 m³ ALGI-CID Liquid Substituting Agent mixing into pool water and placing 2 DEWAN 20 T floating tablet dispensers.

Continuous dosing:

To ensure the desired disinfection effect, DEWAN-20 CONCENTRATION should be kept at a constant 8 mg / l value!
During the first two weeks of operation, the DEWAN-20 T concentration should be checked every two days. (Use DEWAN-20 / ph TESTER to measure).
If the DEWAN-20T concentration drops to half the prescribed value (4 mg / l), the dosage should be repeated.
Optionally, DEWAN-20 T should be administered once a week by placing the tablet in a floating dispenser. Concurrently with the tablet, 40 ml / 10 m³ for an indoor swimming pool, 60 ml / 10 m³ of ALGI-CID softener added in the outdoor pool.
