Pool and Spa Water Test Strips, Bottle of 50 Tests for Water Chemistry Checks with Bleach-Out Warning
Pool and spa water test strips make routine water chemistry checks straightforward: dip a strip, let the colors develop, then compare the pads against the chart on the bottle. PoolCheck® supplies 50 tests per bottle for swimming pool and hot tub maintenance.
The bleach-out warning turns the strips black when chlorine is excessive, helping flag a condition that needs attention. The dip-and-compare process requires no digital reader, and the listed scales cover free chlorine, bromine, total alkalinity and pH.

Frequently Asked Questions
Can these test strips be used in a hot tub as well as a swimming pool?
Yes. These water test strips are intended for swimming pools, spas and hot tubs, so the same bottle can support checks in either setting.
How do I take a reading with these pool test strips?
Dip one strip for 5 seconds using a gentle back-and-forth motion, remove it and shake once briskly. Wait 15 seconds, then compare the pads with the bottle chart within the next 30 seconds.
What does it mean if a test strip turns black?
A black strip is the bleach-out warning for excessive chlorine. Treat that indication as a warning rather than interpreting it as a zero-chlorine result.
Which water chemistry readings are listed for these strips?
These strips list scales for free chlorine, bromine, total alkalinity and pH. Compare each test pad with its corresponding scale on the bottle.
How many tests are in one bottle?
One bottle provides 50 tests. Use one test strip for each water check.
