Red 4-in-1 Test Strips, 50 Count

Tests for: Total Bromine, pH, Total Alkalinity and Total Hardness. If you’re using bromine in your spa, make sure you have AquaChek Red on hand. This test strip also tests for total hardness, which is especially important for spas and hot tubs. The flip-top cap dispenses one strip at a time, making it quick and easy to grab a strip and start your test.
