How do you use a test strip for a hot tub?

Turn the hot tub on, cover it and let the water circulate for eight to 12 hours or overnight. Dip another test strip into the water and check for free chlorine. If the strip shows the presence of free chlorine, your hot tub is now clear of bacteria.

Tips for using Test Strips:

  1. Submerge the strip 6″ under water for two (2) seconds, and remove with the pads facing up.
  2. Shake ONCE to remove excess water.
  3. Place test strip up to the color legend and read immediately in this order: FCl > Alk > pH > CH.
  4. Add the appropriate chemicals indicated.

can you use bromine test strips for chlorine?

Yes, you can use a pool test kit and extrapolate the bromine reading in a pool or spa. If you have a DPD test kit, you need simply multiply the test result by 2.25 to obtain the bromine equivalency. This works because bromine is over twice as dense as chlorine.

How do I test my hot tub for bacteria?

Turn the hot tub on, cover it and let the water circulate for eight to 12 hours or overnight. Dip another test strip into the water and check for free chlorine. If the strip shows the presence of free chlorine, your hot tub is now clear of bacteria.

Does adding chlorine increase pH?

Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. So the net effect on pH is zero (or almost zero).

What do the colors on the pH strips mean?

The colors on a pH strip measure the concentration of hydrogen ions in a solution or in soil. The color on the strip determines the acidic or alkalinity state of the item being tested.

How often should you test your hot tub water?

3 times per week

How accurate are pool test strips?

Pool test strips are accurate but the accuracy depends on a few factors. Some pool experts say that strips can be more accurate than drop kits because with drop and liquid testing kits, there’s much more room to make errors. You only need to add one extra drop of liquid and your test will be inaccurate.

How do I know if my pool chlorine is too high?

TESTING VERY HIGH CHLORINE LEVELS If this happens, dilute your test sample with half distilled water (or chlorine-free water), and multiply by two. For example, shake out half of the water test vial and refill with distilled water, then multiply your test result x 2 to obtain readings above 10 ppm.

Can you use pool strips to test drinking water?

Swimming pool test kits CAN get used to test tap water, but most drinking water experts frown upon using them for that purpose. Typically your basic liquid reagent pool water test kits use OTO as the chlorine testing chemical and that chemical tests for total chlorine in rather non-precise increments.

Is bromine the same as alkalinity?

Bromine has a low pH of around 4, and using bromine tablets will slowly lower pH and alkalinity over time, requiring additions of a base chemical to raise pH and alkalinity. The same can be said for chlorine tablets, which have a pH even lower, around 3.

How long do spa test strips last?

Test strips typically have a 24-36 month shelf life. Look on container bottom for expiry date. Store reagents and test strips in a cool, dry location, out of direct sunlight.

What does free chlorine mean on a test strip?

Most chlorine test strips measure either free chlorine or both free chlorine and total chlorine in a sample of water. The amount of free chlorine present in drinking water indicates whether or not it is safe to drink.

What is free chlorine?

Free Chlorine is the type that we commonly test for to determine the proper chlorine levels in pool water. Free Chlorine is also the chlorine that is still available to sanitize your water. Combined Chlorine is the chlorine that has already been “used up” sanitizing your water. And Total Chlorine is the sum of the two.

How do you test bromine levels in a spa?

Testing Bromine Levels To determine the current level of bromine in your hot tub water, use a bromine test kit available from your local spa dealer. Follow the instructions on the package and be sure to ask your dealer any questions you have about the water purification process.
