SpaGuard Chlorinating Concentrate | Spa Sanitizer

SpaGuard Chlorinating Concentrate delivers the proven sanitizing power of chlorine in a fast-dissolving granular form built specifically for spas. Sanitizer is the single most important part of spa care — it's what keeps the water safe by controlling the bacteria and microorganisms that thrive in warm water. Chlorinating Concentrate is a simple, reliable way to maintain that protection.

What makes it especially convenient is that it does two jobs at once: it acts as both a sanitizer and an oxidizer, so a single product keeps the water both safe and clear without needing a separate routine product for each task. It's also pH neutral, which means maintaining your sanitizer won't constantly drag your pH out of range — a real advantage over harsher chlorine types. And because it dissolves quickly, it can be added directly to the spa with no pre-dissolving.

It's a stabilized chlorine, so the active is protected against being burned off quickly by heat and aeration — a good fit for the demanding conditions of a hot tub. Available in three sizes — a 14 oz bottle for lighter or seasonal use, a 2 lb bottle, and a 5 lb bottle for year-round owners who want the best per-dose value.
