Use rapid-impact granulated chlorine for chlorination (we recommend dichloro or trichloro).

- Pour in using a sufficient amount in accordance with the instructions on the tin, to raise the chlorine to 10 mg/l (ppm). As an indication, fill 2-3 kg dichloro for every 50 m3 water in practice.
- With recirculation running, pour half into the skimmers and distribute the remainder in the vessel. It is not necessary to dilute it.
- Leave filtration in place during complete replacement of the water. This will depend on the flow from the pump, but the normal time is 4-5 hours.
- Shut off the pump and wait 8 hours (till next day).
- If there are algae, rub the walls and base down with a brush.
- Take the base cleaner and clear any residues of algae and dirt out of the pool (so that it does not pass through the filter, nor run back into the pool).
- Carry out washing of the filter and rinse.
- Start up the system as normal. Once the chlorine concentration falls below 2 mg/l (ppm) you can use the pool. If you use dichloro, this will be within approximately 48 hours or, with trichloro, from 2 to 3 days.
