The mineral sanitizer that cleans and softens hot tub water inside your filter cartridge. While you’ll add dichlor or bromine separately, you’ll need half the usual amount, because our FROG minerals are active sanitizers. The result is you kill bacteria two ways – with minerals and a low level of chlorine or bromine. We call it Fresh Mineral Water®∞ because it looks and feels amazing.
Ah, your hot tub, shouldn't caring for your hot tub be as pleasant and worry-free as using it? We think so. Which is why we created, FROG Serene. FROG Serene takes away the measuring and the mess. The daily chore of adding chlorine granules. Serene takes away the smell of Chlorine and the harsh feeling water that irritates skin, fades swimsuits, and ruins surfaces. Serene takes away the big swings in pH and the heavy Bromine use. Serene takes away the dull cloudy water and fears about bacteria. With FROG Serene, what you are left with is serenity. Water that feels soft and gentle to the skin. Thanks to a proprietary blend, of fresh minerals and low bromine, you're left with crystal clear water and weeks of maintenance-free, worry-free relaxation. And using FROG Serene in your hot tub is calmingly simple too. Instead of spooning in granules or filling floaters, simply adjust the pre-filled Bromine Cartridge, then replace when it's empty, in about 2-4 weeks. The long-lasting Mineral Cartridge does the rest of the work for you, and you don't have to replace it for 4 months. Because everything is pre-loaded, you get complete and precise water care. FROG Serene comes with its own start-up shock called, The FROG Jump-Start and a bottle of FROG Test Strips, to dial in the comfortably low bromine level. So instead of monitoring constantly, you enjoy endlessly.
How to Raise Bromine Levels in a Hot Tub with FROG Serene®?
Check to see if the bromine cartridge is empty.
Determine if the bromine cartridge setting is too low.
Evaluate your spa usage.
Clean your filter.
Check the expiration date on your test strips or kit.
Most test strips and testing reagents last only 12 to 18 months. After that date, they may not register readings properly. In addition, if you are putting wet hands into the test strip container, you could be contaminating the strips which will shorten their life even further.
