SpaGuard Anti-Foam | Instant Spa Foam Remover

• 1 x SpaGuard Anti-Foam — 1 Pint (16 oz liquid concentrate)

Note: Anti-Foam is highly concentrated — a little goes a long way (about 1/2 oz per application). A spray bottle gives the best, most even results. Shake well before each use, keep the bottle tightly sealed, and store in a cool, dry place.

• Works on contact — begins eliminating foam the instant it's applied.
• Highly concentrated — a small amount clears a lot of foam, so the bottle lasts.
• Apply directly to the foam — target the problem spot and watch it collapse.
• Simple to use — no waiting, no circulation cycle required to see results.
• Spray-bottle friendly — decant into a spray bottle for the most even application.
• Works with every common sanitizing system — chlorine, bromine, ozone, and biguanide.

Foam forms when the water's surface tension drops. Body oils, lotions, soaps, and detergents act as surfactants — they let air get trapped in stable bubbles instead of popping the way they would in clean water. The agitation from jets and aeration whips those bubbles into a layer of foam on the surface.

SpaGuard Anti-Foam is a fast-acting foam suppressant. Applied directly to the foam, it disrupts the bubble walls so they collapse on contact, clearing the surface almost immediately. It treats what you can see right now — it doesn't remove the oils and surfactants causing the foam, which is why recurring foam points back to water chemistry (especially low calcium) or to water that needs replacing.

Pro Tip: Anti-Foam handles the surface; your filter and a periodic shock handle the cause. Keeping the filter clean and oxidizing regularly removes the oils and residue that create foam in the first place, so you'll reach for Anti-Foam far less often.

1. Shake the bottle well before use.
2. Add 1/2 oz to the spa water, applying directly to the foam.
3. Repeat as necessary until the foam clears.
4. For best results, apply using a spray bottle for even coverage.

Pro Tip: Start with less than you think you need — Anti-Foam is concentrated, and a light application usually clears the surface. Overdosing wastes product and can leave a residue. If the foam returns quickly after treating, that's a signal to check calcium hardness or consider a water change rather than adding more.
