Leisure Time Foam Down | Spa Defoamer

Leisure Time Foam Down is a concentrated non-oil-based foam suppressant formulated specifically for spas and hot tubs. Active chemistry: a proprietary blend of non-oily anti-foaming agents that collapse existing foam on contact and help prevent immediate re-foaming. The "non-oil" detail matters — cheaper general-purpose defoamers use oil-based silicones that knock down foam but then leave a thin oil film on the water surface and filter, which often makes the foam problem worse over the next few uses. Foam in a hot tub isn't normal — and it's not the same thing as bubbles. Bubbles from jet aeration are clear, large, and disappear within seconds of surfacing. Foam is white, persistent, and accumulates several inches deep within minutes of turning on the jets. Foam means soaps, body lotions, detergent residues, or organic residue have built up in the water to the point where surface tension is no longer keeping bubbles intact and they're forming a stable foam matrix instead. Once foam starts, it gets dramatically worse with every minute of jet operation. Foam Down attacks active foam immediately. A small spray directly onto the foam surface — about ½ oz. at a time — collapses the foam matrix within seconds, restoring a normal water surface. Keep a bottle on hand for hot tub parties, first dates, and any other occasion where suddenly having a tub full of bubbles would be embarrassing. The 32 oz size is enough for years of occasional on-demand use. Pro Tip: Foam Down treats the symptom, not the cause. If your spa foams every time the jets come on, you have an underlying water chemistry problem — most commonly low calcium hardness (below 150 ppm), accumulated organic residue from bathers, or fill water that's simply past its drain-and-refill date. Repeated dosing of Foam Down on a chronically foaming spa is a band-aid. The real fix is to test calcium hardness, dose Enzyme to clear organics, and drain-and-refill if the water is more than 3–4 months old. Brand Leisure Time®
