SpaGuard Spa Chlorinating Concentrate Granular Chlorine Sanitizer — 5 lb Single Pack, Fast-Dissolving pH-Neutral

SpaGuard Spa Chlorinating Concentrate is a fast-dissolving, granular chlorine sanitizer and shock designed for routine disinfection and periodic oxidation of hot tub water.

These concentrated granules come in a 5 lb single pack and are formulated to dissolve quickly when added to moving spa water, giving owners a straightforward way to maintain clear, sanitized water. The product is pH-neutral so it won’t disturb a balanced water profile when used as directed. Use regular doses to keep bacteria and contaminants under control, and larger "shock" doses to oxidize organic load after heavy use or when water appears dull.

How should I add SpaGuard Chlorinating Concentrate to my spa?

Add the granules directly to the spa while the pump and jets are running so the product dissolves and disperses evenly. Avoid adding the powder to a single spot near bathers; circulate for several minutes after dosing to ensure full distribution. Always follow the dosing directions on the label for your spa volume.

• Add while pump is on to promote rapid dissolution and even coverage.
• Measure doses based on your spa’s gallons and the label instructions.
• Use a shock (higher) dose after heavy usage or visible cloudiness.

What makes this chlorinating concentrate different from other sanitizers?

This formula is a granular, concentrated chlorine designed specifically for spas, combining quick dissolution with reliable sanitizing action. It functions both as a daily sanitizer in routine amounts and as an oxidizer in higher shock doses, reducing the need for separate products. The pH-neutral composition helps minimize disruption of your balanced water chemistry.

• Granular, quick-dissolving formula for ease of application.
• Dual-purpose: routine sanitizer and periodic shock/oxidizer.
• pH-neutral to help preserve balanced water chemistry.

How often and when should I use the Chlorinating Concentrate?

Use a maintenance dose regularly—typically after each spa use or on a schedule recommended by your spa’s care routine—to maintain sanitizer levels. Apply shock doses after multiple users, heavy soiling, or if the water loses clarity. Regular testing of free chlorine and pH will tell you when to top up or shock.

• Routine dosing: maintain sanitizer levels according to label/testing.
• Shock dosing: after heavy use, visible cloudiness, or odor.
• Test water frequently to guide additional applications.

Who is this for? SpaGuard Spa Chlorinating Concentrate is intended for hot tub and spa owners who want a straightforward, concentrated chlorine solution that dissolves quickly and serves double duty as both sanitizer and oxidizer. It’s a practical choice for people who prefer a single, easy-to-apply product to maintain clean, clear water, and for service professionals managing multiple spas who value consistent, pH-neutral performance without extra balancing steps.
