Swimming Pool Chemicals and Water Treatment

Dolphin Leisure supply only the finest quality swimming pool and spa water treatments.

Our own Dolphin Leisure brand of swimming pool chemicals are packed for us in the UK by one of the major suppliers and the products will always reach you in the peak of condition.

PLEASE NOTE :  We are unable deliver chemicals or any liquid products overseas. All other items can usually be delivered overseas but please note that there may be an extra carriage charge.

Whatever water treatment you choose to sanitize your swimming pool or hot tub, it  will only be effective with the pH of the water balanced within the range of 7.2 to 7.6 parts per million. Also, whatever system you choose will require regular shock dosing (oxidizing), the frequency of which will depend on the bather load.

Non chlorine products such as PoolSan or Blue Crystal are safer than traditional chlorine treatments and are easy to use. Hygiene without chlorine usually means no stinging eyes, skin irritation, bad taste or smells.

Blue Crystal avoids the necessity for daily checks and dosing. Used with a shock dose treatment, the Blue Crystal products provide an excellent alternative to chlorine.

PoolSan  - 100% Chlorine Free Swimming Pool and Spa water treatment. PoolSan is a safe effective chlorine replacement that offers bacteriology control in commercial or domestic pools and hot tubs.

We also recommend Aquafinesse for your spa or hot tub. Simply apply the liquid once a week, keep an eye on the small tablet dispenser and that's it. The super soft feel to the water results in a  much more pleasant bathing experience.
