Foam may appear in your spa for several reasons, including a chemical imbalance or a build-up of surfactants (personal care products, skin cells, etc.) in the water.
A chemical water analysis at your Sima dealer (free of charge) is the first step to remedy the situation. Upon analysis, we will advise you on the appropriate solutions. Whether it is with the Calypso #5 Foam Destroyer or simply with some wise advice, your Sima dealer will be able to help you.
