Maintaining your pool or hot tub chemistry can be challenging. Liquid water tests are messy and complicated and require multiple steps to perform before you can get your full results. After you fill a vial and count the drops, deciding the color match can be tricky. And keeping the bottles and comparator around and ready, can be troublesome too. Wouldn’t it be nice to have all the materials in one spot? Thankfully, AquaChek® Test Strips do just that. It’s simple to remove one test strip that has 4 reactions on it. Dip the entire strip into your pool or hot tub for a few seconds and compare to the chart on the bottle. The little pads on the strip react with the water, changing color in proportion to the concentrations all at once. After this step, typically you would need to find a dosing chart and perhaps a calculator to figure out what you need to do to the water to keep it balanced or sanitized so everyone can enjoy it again!

The question then becomes, “Now What?!” Now, that’s where AquaChek Smart can be your go to resource and provide you with what you need. Dip your strip then match the pads to the pads on your smartphone or iPad, hit Prescription and instantly you have a set of step by step directions on what you need to do!

Nice idea Needs liquid recommendation

We are having trouble changing our pool type to salt cell and also would like the calculations for liquid acid. This only gives the recommendation for dry muriatic acid. Would rather not have to calculate that somewhere else. Great concept but not quite there yet. We like the visual effect of strip itself.

Not impressed - Bad app

I'm not impressed with this app. Most importantly, the advice it gives is WRONG. I entered that I had an alkalinity level of 199, and a ph of 7.2 for my 24' pool (roughly 13,600 gal.). The report told me that I needed to add 17 lbs. 2 oz. of dry acid to the pool to lower the alkalinity!!! That would probably melt the vinyl in my pool.

The app is also buggy, and some basic functionality is missing. For instance, the decimal point button is missing where you input the chlorine levels. For those of us using a low chlorine system, that decimal point is important.

AquaCheck makes a great digital tester, and I haven't had any problems with their other products. Too bad that they didn't spend more time on this app.

This app does exactly what it says it will do! It is very easy and far superior to other test strip apps I have tried. They do not even make you sign up for an account, so all you do is download the app and it's ready to use.

You enter your pool information, and it gives you your gallons. After you enter your test strip information, it tells you exactly how much of each chemical to add.
