Spa Frog test strips are specifically designed to precisely measure the lower levels of chlorine or bromine used with the Spa Frog Serene floating system or in line system built into some hot tubs. Bottle contains 50 test strips.
These test strips test for:
- Free Chlorine or Bromine
- Total Alkalinity
- pH
- Total Hardness
SPA FROG Serene keeps your hot tub clean while eliminating the work and the guesswork. Instead of spooning in chlorine daily, you simply replace a pre-filled Bromine cartridge about once a month. FROG Serene works by killing bacteria with bromine and the mineral cartridge conditions the water for better water quality. The resulting Fresh Mineral Water® has a completely different quality that provides the serene feeling you’re looking for.
