Frequently Asked Questions

Why is my spa foaming?

Spa foam is caused by surfactants — substances that lower the surface tension of water. Common sources include body oils, sunscreen, moisturisers, cosmetics, hair products, laundry detergent residues on swimwear, and organic waste from bathers. As the jets agitate the water, these surfactants create foam. While anti-foam treats the symptom quickly, persistent foaming usually indicates the water needs a non-chlorine shock treatment or a full water change to remove the underlying contamination.

How do I use Zodiac Spa Anti Foam?

Add a small amount of Zodiac Spa Anti Foam directly to the foaming area of the spa water with the jets running. The ultra-concentrated formula acts quickly — start with a small dose (a few millilitres) and add more if needed. Avoid overdosing, as excess anti-foam can itself contribute to water quality issues over time.

Will anti-foam affect my water chemistry?

No — Zodiac Spa Anti Foam is formulated to eliminate foam without affecting pH, total alkalinity, or sanitiser (chlorine or bromine) levels. You do not need to retest or adjust your water chemistry after dosing.

When should I do a full water change instead of using anti-foam?

Anti-foam is a quick fix for occasional foaming. If your spa foams persistently despite regular anti-foam treatment, or if the water appears cloudy, has an odour, or is difficult to balance chemically, it is time for a full drain and refill. As a general guide, spa water should be changed every 3–4 months depending on usage and bather load.
