A hot tub shock will remove dissolved dissolved organic matter from the hot tub water. This is 'stuff' that gets dissolved in the water and can't be removed by your sanitiser or by the filter. For example, perspiration and body oils. It there is a significant amount of dissolved organic matter in the water it will become dull and "lifeless" and will eventually start foaming.

In contrast to a shock product, a water clarifier will help to remove tiny solid particles of contaminants from the water and is often said to make the water sparkle.

A anti-foam will stop the water foaming, but it should only be used as a last resort and if you find it necessary to use an anti-foam on a regular basis is is probably time to change the water!

surespa FoamAway - 1lt More Information
£16.35

Foaming in hot tub water can be caused by significant organic matter from bathers entering the water after heavy use. It is also often caused by make-up, body lotions and other contaminants that really shouldn't be allowed to enter the water at all.

surespa FoamAway has been especially formulated to damp down foaming that occurs when the jets are turned on in contaminated water.

Anti-foam inevitably dulls the water and is best avoided if possible. If your water is foaming first make sure that the problem cannot be rectified by shocking the water and cleaning the filters.

You can, but we recommend that you don't, use this product as a foam preventer - it's far better just to avoid contaminating the water if at all possible!
