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.

SpaGuard® Brand FAQs
What is SpaGuard?
SpaGuard is a professional-grade brand of spa and hot tub water care products — sanitizers, shocks, balancers, and water enhancers — formulated specifically for spas rather than adapted from pool chemicals. The line is designed to work together as a complete system for clean, clear, comfortable water.
Who makes SpaGuard?
SpaGuard is part of the BioGuard family of water care brands, a long-established name in pool and spa chemistry. That backing means the formulas are professionally developed and tested, with a reputation built over decades in the industry.
What water care systems does SpaGuard offer?
SpaGuard supports three complete care methods: a chlorine system, a bromine system, and the Soft Soak TRIO system. Each is a coordinated set of products, so you can match your routine to the sanitizer you prefer.
What makes SpaGuard different from generic spa chemicals?
SpaGuard products are engineered for the unique demands of hot, agitated, heavily used spa water, and they're built to work together as a system. That coordination delivers more reliable, repeatable results than mixing unrelated single products.
What is ALEX water testing?
ALEX is SpaGuard's exclusive computerized water-analysis tool used by its dealers. A quick water sample produces a precise read on your spa's chemistry and a tailored recommendation, taking the guesswork out of what to add and when.
Why buy SpaGuard from an authorized dealer?
SpaGuard dealers are trained on the brand's products and water-care technology, so you get expert advice alongside genuine product. They can run an ALEX analysis, troubleshoot issues, and recommend exactly what your water needs.
