Out of stock
The 200g Spa Frog Bromine cartridge is for use in spas with special built in Spa Frog in-line feeders. These cartridges give you 50g more bromine than the traditional yellow cartridges found in the floating system.
The 200g cartridge should last roughly 3-4 weeks depending on use and size of the spa. We recommend leave the cartridge open to setting 3 or 4 for average size hot tubs. For spas over 400 gallons setting 5 should be used.
Adding a New Bromine Cartridge
When adding a new cartridge to your spa it is critical to establish a bromine bank. You do this by opening the bromine cartridge to setting 6 (all the way open) for 12 hours. This allows a large amount of bromine to be released into the spa.
After 12 hours adjust down to the appropriate level for your size spa. Then add 2oz of non-chlorine spa shock. This will help activate the bromine in the spa water.
