Leisure Time Foam Down | Spa Defoamer

• (1) Leisure Time Foam Down — 32 fl. oz. (1 quart) liquid concentrated foam suppressant
• Child-resistant flip-top cap for direct-spray application
• Dosing chart and application directions printed on the bottle label

• Eliminates foam on contact — collapses existing foam within seconds of application
• Non-oil-based formula — won't add to the underlying residue problem the way oil-based defoamers do
• Helps prevent immediate re-foaming after dosing
• Highly concentrated — only ½ oz. needed per application
• On-demand spot treatment — not part of weekly maintenance; use only when needed
• Spray bottle application option — transfer to a spray bottle for more precise targeting of foam patches
• Specifically formulated for hot water — most pool defoamers break down at spa temperatures; Foam Down is engineered for them
• Universal sanitizer compatibility — works with chlorine, bromine, ozone, mineral cartridge, and biguanide systems
• No spa downtime — soak immediately after dosing
• Made in the USA by Leisure Time, a trusted name in spa chemistry for over 40 years

Foam is a stable matrix of bubbles held together by surface tension. In clean water, jet-driven bubbles rise to the surface and immediately pop — they don't form foam because there's nothing in the water to hold the bubble walls together. When soaps, lotions, body oils, or detergent residues accumulate in the water, those organic surfactants reduce surface tension and coat the bubble walls with a flexible film that prevents them from popping. Each new bubble joins the stack instead of collapsing, and within minutes you have several inches of foam covering the entire water surface.

Foam Down uses non-silicone anti-foaming agents that work by disrupting the surfactant film holding the foam together. The agents spread rapidly across the foam surface — that's why a spray application works so well — and chemically destabilize the bubble walls, causing the foam matrix to collapse from the top down. Existing foam disappears in seconds, and the residual anti-foam activity in the water helps prevent immediate re-foaming during the same session.

The "non-oil-based" distinction is the technical advantage. Many cheap general-purpose defoamers use silicone oils that knock down foam by coating the water surface with a thin oily layer. The foam disappears, but the oil residue then accumulates on the spa shell, the filter cartridge, and the waterline — feeding the next foaming event and shortening filter life. Leisure Time Foam Down's non-oil chemistry avoids that trade-off; it kills the foam without leaving residue that contributes to future problems.

Pro Tip: If you're using Foam Down more than two or three times between drain-and-refills, treat it as a diagnostic flag. The most common root causes — in order — are: (1)laundry detergent residue on bathing suits(rinse suits in plain water before getting in), (2)lotions and sunscreens applied within an hour of soaking, (3)low calcium hardness(test with a strip — should be 150–250 ppm), and (4)water past its 3–4 month refill date. Fix the root cause and you won't need Foam Down again for months.

Standard Foam Treatment

1. Shake the bottle well before using.
2. Add approximately ½ oz. of Foam Down directly into the foaming area. The foam will collapse within seconds.
3. Repeat as necessary if foam returns during the same session.
4. Soak immediately if desired — no waiting period.

Spray Bottle Application (Recommended)

1. For more precise targeting, transfer a small amount of Foam Down to a clean spray bottle.
2. Spray directly onto foam patches as they form.
3. This method uses less product per application and reaches foam in corners and around jets more effectively than pouring.

Preventing Repeat Foaming

Foam Down is an on-demand treatment, not a weekly maintenance product. After dosing, if foam returns within hours or with the next use, address the underlying cause:

• Test calcium hardness with a quality test strip — should read 150–250 ppm. Low calcium is a leading cause of chronic foam.
• Test pH and alkalinity — out-of-balance chemistry contributes to foam formation.
• Dose Leisure Time Enzyme at 1 oz. per 250 gallons to break down accumulated organic residues.
• Check fill water age — if you're past 3–4 months on the current fill, it's time for a drain and refill.
• Rinse bathing suits in plain water (no detergent) before each soak.

Storage & Handling

• Store in original container in a cool, dry, well-ventilated area
• Keep tightly closed when not in use
• Protect from freezing — liquid formula can lose effectiveness if frozen
• Keep out of reach of children and pets
• Do not mix with other chemicals in undiluted form — always apply directly to spa water or foam
• Shake well before each use — separation is normal and not a sign of degradation

Pro Tip: Keep Foam Down within arm's reach of the spa, not in the chemical storage cabinet across the yard. The whole point of an on-demand defoamer is that it works in 10 seconds when you need it — which usually means in the middle of a soak with guests, not during a planned chemistry session. A small bottle stashed in the spa cabinet (out of direct UV and freezing temperatures, but accessible) saves you a long, foamy walk every time.
