california jeanne: I like these better than other brands I've tried. You can easily read the results and don't have to wait to read them.

Brett: I have recently switched my spa over to Nature2 spa sanitizer and you use Potassium Peroxymonosulfate 'MPS' as an oxidizer. These strips are the only ones I've found that measure the MPS level, the Chlorine or Bromine test strips won't.

Only thing I found if you do add chlorine which I do if the tub is left unattended for a period of time the strips will give you a false reading until the chlorine level drops off.

Chlorine or Bromine strips will show nothing if there is MPS in the water but no Chlorine or Bromine. However the MPS strips show a reading from the chlorine when there is no MPS in the water.

These strips are a must if you are using a mineral sanitizer and MPS as an oxidizer.

Big Papi Jay: Contrary to other opinions, this actually does test for MPS and does not test for chlorine.

So, if you are switching from a Bromine system to Chlorine and if you purchased test strips for your Bromine system, don't throw them away, they will actually work in a Chlorine system and inform you of the amount of chlorine in your hot tub (In other words save the strips).

You still want to get these test strips to ensure your MPS levels are in line.

If you want amazing hot tub water quality follow the steps below:

1.) Use these test strips to test MPS.
2.) Go with chlorine system (Much easier to control levels) and put 1 teaspoon to 1.5 teaspoons of Chlorine dicholr.
3.) Use the Nature 2 system by inserting it into filter channel per the instructions.
4.) Use 1 tablespoon of MPS.
5.) Repeat step 2 and 4 after every hot tub use.
6.) Drain hot tub every 3 months.

TC: Work great with my Nature2 System. Important to use these and not other test strips, because these are the most important readings for the Nature2 low chlorine system, when you're using MPS Shock.

I use this regularly, and it has been very helpful in maintaining my hottub, using the Nature2 system, which we converted from Bacqua Spa to. Couldn't be happier. If you're thinking of getting rid of BacquaSpa, but don't want to use a lot of chlorine, or bromine, the Nature2 system is what you want.

A little expensive at $10 for 50, but i don't use them every day. One of these should last me all winter.

Blair B: Nature2 is a low chlorine system that basically operates the opposite of a chlorinated spa. In a chlorinated spa, chlorine is maintained and added after every use, with a once weekly MPS shock. In a Nature2 spa, MPS level is maintained in the spa and added after every use, with a once weekly chlorine shock. You'll find most test strips measure chlorine, but not MPS. These Nature2 strips measure MPS and PH levels. While they are a little expensive, you'll soon learn how much chemical to add after each use, and probably only need to test weekly.

While I've yet to have a problem with anyone using our spa, some people are sensitive to MPS and can break out in a rash. A Nature2 system is a little more expensive to maintain, but I find it easier than chlorine, and there's very little odor (MPS may have its own slight odor).

Middlebunny: I have tested Alkazone Ph Test Strips for Water, Micro Essential Lab 9800 pHydrion pH Range: 0.0 To 14.0, 100 pH (Strips/Vial, Plastic pH Test Strips), and Nature2's Spa Test Strips. While the Alkazone strips are an improvement over the Micro Essential Lab 9800 pHydrion (pHydrion) strips (which don't work at all), the colors are not as vivid as they appear on the comparison sample on the container. In addition, a solution I knew to be a pH of 9 tested as a 7 using the Alkazone strips. In fact, plain Fiji bottled water tested at a 7 and the pH reading on the Alkazone strips appeared unchanged even after adding alkalizing drops and/or baking soda both of which should have brought the pH above 9.

With the pHydrion strips, plain Fiji bottled water tested between a 3-4 pH while the Fiji bottle claims it is a 7.8 pH. Also, the color of the pHydrion strips does not change consistently throughout the strip. In fact, anything under a pH of 8 will only change the edges of the litmus paper such that the edges will be green while the center remains peach/orange/yellow.

The Nature2's Spa Test Strips appear to work the best for testing water. They appear to be relatively accurate;...
