SHOP BY NEED
Which AquaChek Test Is Right for Your Pool?
These are different testing methods, not interchangeable versions of the same strip. Choose by sanitizer, parameters and how you plan to read results.
AquaChek Yellow Chlorine 4-in-1
Best for routine chlorine-pool checks
Measures free chlorine, pH, total alkalinity and cyanuric acid (stabilizer). A practical everyday strip when those four parameters are your main routine.
Does not replace dedicated calcium-hardness or salt testing. Confirm the parameter list on the exact pack.
AquaChek Select Connect 7-in-1 Kit
For seven readings plus app-assisted interpretation
Checks hardness, total and free chlorine, bromine, pH, alkalinity and cyanuric acid. The Select Connect kit pairs with the brand's photo-scan app.
Buy the kit for the app workflow; verify Select Connect refill strips rather than assuming any AquaChek strip works.
AquaChek Silver 7-in-1 Strips
For broad manual strip testing
The Silver professional line covers seven key pool-water parameters, including free and total chlorine, hardness and stabilizer.
Compare bottle quantity and expiration date. These are visual-read strips, not TruTest reader refills.
AquaChek White Salt Titrators
For sodium-chloride measurement in salt pools
Dedicated titration strips measure sodium chloride, with the manufacturer specifying a 400–7,000 ppm range.
Salt strips do not measure free chlorine or pH; use them alongside a separate sanitizer/balance test.
AquaChek Salt System Test Kit
For owners who need a salt-pool testing bundle
A manufacturer-listed salt-system kit is a useful purchase path when starting a saltwater testing routine.
Check exactly which strips are included; a bundle does not guarantee all chemistry parameters are covered.
AquaChek TruTest Digital Reader
For users preferring electronic strip interpretation
AquaChek offers a dedicated TruTest reader and matching test-strip refills for selected water-balance readings.
TruTest is not a laboratory photometer. Use only its specified strips and follow timing instructions.
AquaChek ShockChek Test Strips
For a targeted check after shock treatment
ShockChek is a distinct product line for checking shock-treatment conditions, not a general seven-parameter replacement.
Do not substitute ShockChek for daily free-chlorine, pH and alkalinity monitoring.
Replacing or servicing an existing system?
Shop the exact compatible component, not a look-alike.
AquaChek flow switch
For a confirmed flow-switch fault
Only replace the switch after checking circulation, pump operation and the system error.
Verify switch model, electrical connector and plumbing compatibility.
AquaChek maintenance components
For a specific maintenance need
Find cleaning accessories or service parts approved for your exact installed model.
Identify the required part number and follow the manufacturer maintenance instructions.
BUYER'S DECISION GUIDE
Choose the AquaChek Test by the Reading You Need
A strip is only useful if it measures the parameter you are trying to manage. These four decisions prevent buying a convenient-looking but incomplete kit.
Match the sanitizer
Chlorine and bromine products are not identical. For a bromine spa, check the bromine-specific strip scale; biguanide systems require their own tests.
Know which readings are missing
Yellow 4-in-1 includes stabilizer but not calcium hardness. Seven-parameter options add breadth; a dedicated salt strip measures sodium chloride.
Choose the reading workflow
Visual strips require comparing colors at the specified time. Select Connect uses an app; TruTest uses a dedicated reader and compatible refills.
Check strip freshness
Confirm expiration, bottle seal, storage directions and pack quantity. Humidity and poor timing can undermine otherwise appropriate tests.

AquaChek Pre-Purchase Checklist
Check these details before buying a bottle, bundle or electronic reader.
- Identify your sanitizer: chlorine, bromine or biguanide.
- List required readings: chlorine, pH, alkalinity, hardness, stabilizer or salt.
- Check whether the product includes the needed strips or requires separate refills.
- For TruTest, confirm the exact compatible strip type.
- Verify strip expiration date, pack quantity and storage instructions.
- Keep a reliable drop-based test method for confirmation when results are unexpected.
For electrical and plumbing installation, follow manufacturer instructions and local codes.
BUYER QUESTIONS
AquaChek Testing FAQs
Answers to the compatibility and sizing questions worth resolving before you place an order.
Do AquaChek Yellow strips measure salt?
No. Yellow 4-in-1 measures free chlorine, pH, total alkalinity and stabilizer. Use a dedicated sodium-chloride strip for salt level.
Does a saltwater pool still need chlorine testing?
Yes. Salt chlorinators produce chlorine, so free chlorine and water balance still require regular testing.
Can I use Select Connect strips in TruTest?
Do not assume compatibility. Select Connect is an app-assisted system; TruTest has designated reader refill strips.
Which AquaChek option checks hardness?
Select Connect 7-in-1 and Silver 7-in-1 include total hardness; standard Yellow 4-in-1 does not.
Are test strips enough for every pool decision?
They are convenient for screening and routine checks. For unusual readings, persistent water problems or precise treatment, confirm with an appropriate independent method.
