FAQ:

Q: How often should you test your hot tub water?

A: Regardless if you are on a chlorine or bromine sanitizing system, it is always recommended to test your hot tub water at least every other day. We recommend testing the water every other day, so that you can always insure that the hot tub levels remain steady, to prevent problems such as cloudy water.

Q: How do you test hot tub water?

A: Test Strips. Test strips are arguably the easiest and most common method of testing the water in your hot tub. You simply take a sample of your hot tub water in a clean glass, dip the strip into the water to moisten the test pads, and then wait for about 15 seconds.

Q: What is the best water test kit for swimming pools?

A: For phosphates you can get a phosphate test kit. Phosphate test kits are great if you think there’s an issue with your pool. Normal pool water testing kits don’t test for this. Swimming pool chlorine is the sanitizer of the pool and should be kept between 2 – 4 ppm. The pool pH should be between 7.2 – 7.8.

Q: What are chemicals for hot tub?

A: If you have a hot tub, you are very familiar with the issues related to the use of chemicals to sanitize your hot tub. The chemicals such as chlorine, bromine, pH up, pH down, shock (hydrochloric acid), clarifier and de-foamers are all used to sanitize and clarify the water.
