When filling your spa for the first time (commissioning) or when refilling after it has been empty for a period, it is strongly recommended that a shock chlorination should be carried out on the cold fresh water. Fi-Clor Spa Shock are ideal products for this purpose as they are unstabilised chlorine donors & will deliver the maximum effectiveness.
The free available chlorine level should be taken to either 25mg/l (ppm) for a minimum of two hours, or 50mg/l (ppm) for a minimum of one hour.
While the spa is being chlorinated to these high levels, the water must be allowed to flow to all parts of the system, regularly monitoring the chlorine residual to ensure that it does not fall below the specified level at any time. Where an air blower is fitted, it should not be run for the first 15 minutes to minimise the formation of aerosols (fine spa water mist).
During shock chlorination, the p H should be maintained within the range of 7.2

Fi-Clor Supercapsules can be used as a regular pool sanitiser
- they are especially recommended for pools that are open all year round. They are enclosed in a protective plastic sleeve making them easy to handle. As the capsule dissolves, chlorine is released from each end of the sleeve. The surface area of the capsule exposed to water remains constant so, unlike normal 200g tablets, you get an even amount of chlorine going into the pool from start to finish. These calcium hypochlorite Supercapsules contain 65% available chlorine, no stabiliser (cyanuric acid) & will not contribute to chlorine lock. Each capsule weighs 300g & should last 3-5 days depending upon water conditions. > For maximum efficiency stabilise the water at the beginning of the season with Fi-Clor Chlorine Stabiliser. Alternatively, use the capsules in conjunction with Fi-Clor Premium 5 multi-functional stabilised chlorine granules which will contribute sufficient stabiliser to guarantee optimum performance after a short period of use.
