I just purchased these test strips from a pool store but I'm having a hard time telling the difference between the colors, is there something better?

These test strips should be used with the digital reader they are designed for. The digital reader will display the numeric values of the pH, alkalinity and chlorine.

Does item # NP207, Aqua Chek Trutest Digital Reader, come with test strips or do I need to purchase test strips separately?

Are the strips single use or can on strip be used multiple times?

Hello Paul. I retrieved this from the Aqua Check site itself - Q: Is posible to use test strips several time (two or more times)? Thank you very much. A : It is not possible to use the test strips again after they have been wetted with sample.  The chemistry is depleted after the first use and the test strip should be discarded.  This page would have many other possible questions and answers you may have

I have issues with hard water and high alkalinity. What can I do? I have lowered Alkalinity with muratic acid but water hardness is a pain

Hello Annette, The only true way to reduce the calcium hardness levels in your pool is partially drain water from the pool and to introduce fresh water. Unfortunately, there is not a product on the market that you can add to your pool to reduce calcium hardness levels.

Going to salt water pool do I use the same test strips as chlorine?
 Reply

A  Answered on 5/25/2016 by InyoPools Product Specialist Alan M.

Yes, the test strips you use to measure the chlorine and pH levels in your pool are the same. You may want to purchase Salt Test Strips to measure the salt content of your pool if your salt system does not provide that information via a digital display.

Is using this meter for checking pool chemical levels accepted the same as traditional testing methods by county and state health departments?

Hello Steve, you would want to use Taylor Water Test Kit Commercial - K2005C.

My meter is 5 years old and I am getting extremely high alkaline results e.g. 220-240. These numbers are 100 ppm higher than when I go to the pool store and they do their readings. My pH and Cl are close. Do I need to replace my meter? I did put in fresh batteries and get the same results.

Hi, Paul. Before replacing the meter, check the expiration date on the strips, and make sure the sensor is cleaned. If both are good then the meter is bad and will need to be replaced.

What is the range of chlorine that the tester will test for? Specifically how high? Thanks, John

The TruTest measures Free Chlorine levels from 0 - 15 ppm.

The strips my meter came with just did not work. We when to the store a perched new ones. still odd flake y results two tests one after the other show very different results. We turn it on then press play ...and wait for the screen to say on again we carefully dip the strip about 8 inches into the pool for about 20 seconds....then place it into the machine We feel cheated.......whats wrong???

Hello Dave.  AquaChek use procedures indicate that the test strip is dipped into the water for 2 seconds, firmly shaken 1 time to remove excess water, then placed pad side down into the test strip window.  The strip is placed into the back of the channel at a 45-degree angle and laid flat.  Be careful not to slide the strip across the viewer window which results in inaccurate readings.  Afterwards, clean the window with the cleaner provided or use a cotton swab.  Attached please find a brief Q&A concerning different readings when using the TruTest Meter.   different readings when testing with my TruTest meter   This Q&A also contains a brief video tutorial.  If further difficulties are encountered, please contact AquaChek at phone 970-278-4951.
