Product Overview

The AquaChek Silver 7-In-1 Test Strips, Part 551236, provide a fast and convenient way to monitor seven important swimming pool and spa water conditions with one simple test strip. Each bottle contains 100 test strips, making this package suitable for homeowners, pool-service professionals, property managers, hotels, apartment communities, and commercial pool facilities.

AquaChek Silver test strips measure total hardness, total chlorine, total bromine, free chlorine, pH, total alkalinity, and cyanuric acid stabilizer. Checking these water conditions regularly helps identify chemical-balance problems before they lead to cloudy water, scaling, corrosion, reduced sanitizer performance, algae growth, or swimmer discomfort.

The strips are easy to use and require no liquid reagents, test tubes, droppers, or mixing. Simply dip one strip into the pool or spa water, remove it immediately, hold it level, and compare the developed colors with the chart printed on the bottle. Results are available within seconds, allowing quick chemical adjustments when needed.

Water Conditions Tested

Each AquaChek Silver strip measures:

• Total hardness
• Total chlorine
• Total bromine
• Free chlorine
• pH
• Total alkalinity
• Cyanuric acid

Testing all seven parameters provides a broader understanding of pool or spa water balance than sanitizer-only test strips.

Benefits

Routine testing helps keep pool and spa water clean, comfortable, and easier to maintain. Proper sanitizer levels help control bacteria and algae, while balanced pH and alkalinity support swimmer comfort and protect equipment and pool surfaces.

Monitoring total hardness can help prevent scale buildup or corrosive water conditions. Cyanuric acid testing is especially useful in outdoor chlorine pools because stabilizer helps protect chlorine from sunlight. However, excessive stabilizer may reduce chlorine effectiveness, making regular testing important.

The 100-count bottle provides enough strips for frequent testing throughout the swimming season. The compact design also makes it convenient for service vehicles, maintenance carts, equipment rooms, and home storage.

Specifications

Testing Instructions

Collect water from approximately elbow depth and away from return jets, skimmers, chemical feeders, or freshly added chemicals.

Remove one strip without touching the test pads and immediately close the bottle. Dip the strip into the water and remove it right away. Hold the strip level and wait for the colors to develop according to the instructions on the bottle. Compare each pad with the matching color chart.

For consistent results, test under similar circulation conditions and at approximately the same time of day.

Storage Information

Keep the bottle tightly closed and store it in a cool, dry area away from direct sunlight, moisture, excessive heat, and pool chemicals.

Do not handle strips with wet fingers, and never return a used strip to the bottle. Moisture exposure can affect the unused test pads and reduce accuracy.

Confirm Before Ordering

Verify that:

• You need a seven-parameter water test.
• Your pool or spa uses chlorine or bromine.
• You require cyanuric acid testing.
• A 100-count bottle meets your testing needs.
• The strips can be stored in a dry location.

Warranty Information

Manufacturer coverage applies to qualifying defects in materials or packaging. Coverage does not apply to expired strips, improper storage, moisture exposure, contaminated test pads, misuse, or inaccurate results caused by incorrect testing procedures.
