"Approved for all Wooden Hot Tubs, Pools, and Spas"
The Precision Sanitizer for Wooden Hot Tubs & Spas
When it comes to sanitizing a hot tub, you have two choices: slow-dissolving tablets or fast-acting granules. While tablets are convenient, they lack control.
Northern Lights Bromine Granules give you immediate command over your water purity.
This concentrated granular formula is designed to dissolve on contact with water.1 It immediately attacks bacteria, algae, and organic waste without waiting for a tablet to break down. Because it dissolves instantly, there is zero risk of a "bleaching spot" forming on your liner or wooden staves, making it the #1 Recommended Sanitizer for Cedar Hot Tubs.
The "2-Part System" Replacement
For years, spa owners loved the "2-Part Liquid Bromine" method (Sodium Bromide + Activator). Unfortunately, those products have been largely discontinued due to regulations.
-
The Solution: These granules are the direct replacement. They provide the same "Instant Kill" capability and high effectiveness in hot water, but in a shelf-stable powder form.
Granules vs. Tablets: Why Switch?
-
No Floater Required: You don't need a plastic dispenser bobbing around your tub. Just sprinkle the dose directly into the filter well.
-
Instant Shock: If you have a heavy bather load (e.g., a party), tablets can't keep up. Granules boost your sanitizer levels instantly to handle the extra people.
-
Safe for Wood: Plastic floaters often get stuck in one corner. If they rest against a cedar wall, the acidity can rot the wood. Granules eliminate this risk entirely.
Pro Tip: The "Bank & Shock" Method
To get the most out of this product and save money, use the Bromine Bank method:
-
Establish the Bank: Use these Bromine Granules to build your initial sanitizer level.
-
Maintain: Instead of adding granules every single day, use [Oxy-Pur / Oxy-Out] (Shock) after each soak. The shock "reactivates" the dead bromine in the water, turning it back into a killer sanitizer.
-
Top Up: Only add more Bromine Granules when your test strip shows the level has dropped below 3 ppm even after shocking.

Add directly to the water, granular form dissolves and activates almost immediately!
