Discontinued Product The Jack's Magic TK044 Sequest Test Kit has been discontinued. Jack's Magic has also discontinued the TK069 Sequest #1 tablets required to perform the test. Because the necessary tablets are no longer being produced, there is currently no complete direct replacement kit that performs the same Jack's Magic sequestrant-residual test. Jack's Magic Part TK044 Jack's Magic TK044 Sequest Test Kit The Jack's Magic TK044 Sequest Test Kit was a professional pool-water testing kit used to measure the remaining concentration of compatible sequestering agents in swimming-pool water. It helped service professionals determine when additional sequestrant maintenance treatment was needed to help control dissolved metals, scale and staining. What Did the TK044 Test? The TK044 was designed to measure the residual level of compatible sequestering chemicals already present in pool water. It was not a standard iron, copper, manganese, pH, alkalinity or chlorine test. Its purpose was to help determine whether enough active sequestrant remained in the water to continue helping keep dissolved metals and minerals under control. What Was Included? Sequest #1 test tablets Sequest #2 liquid reagent 10 mL titration vial Direct-reading titrator Stirring rod Protective test-kit case Product Identification This discontinued listing is retained to help pool owners and service professionals identify the original Jack's Magic sequestrant test kit, understand its purpose and evaluate current maintenance options. Manufacturer Jack's Magic Part Number TK044 UPC 734040080257 Product Status Discontinued Alternatives to the Discontinued TK044 Test Kit 1 Follow the Sequestrant Manufacturer's Maintenance Schedule When direct residual testing is unavailable, the most practical approach is to maintain the pool according to the dosage and maintenance schedule printed on the specific sequestrant product. Record the initial treatment date, pool volume and subsequent maintenance doses to avoid unintentionally allowing protection to lapse. 2 Test the Pool for Dissolved Metals A professional pool store or water-testing laboratory may be able to test for iron, copper, manganese and other metals. This does not directly measure the remaining sequestrant concentration, but it can identify the metals that must be managed and help guide the treatment plan. 3 Use a Jack's Magic Stain Identification Kit When visible staining is already present, a Jack's Magic Stain Identification Kit may help identify an appropriate stain-treatment category. This is not a replacement for the TK044 and does not measure sequestrant residual, but it may help determine the next treatment step for an existing surface stain. 4 Select a Sequestrant for the Pool's Specific Conditions Jack's Magic offers different sequestrant products for different pool conditions, including products commonly selected for general metal control, fresh-plaster pools and saltwater pools. The correct product depends on the pool surface, sanitizer system, known metal content and staining concern. Important: A standard pool or spa test kit does not measure sequestrant residual and should not be presented as a direct replacement for the TK044. Tests for iron, copper, calcium hardness or phosphates measure different water conditions and cannot provide the same reading as the discontinued Jack's Magic Sequest Test Kit. Recommended Maintenance Approach Confirm the pool's water volume before calculating treatment doses. Test and balance pH, total alkalinity, sanitizer and calcium hardness. Identify whether iron, copper, manganese or scale is the primary concern. Select a sequestrant that is appropriate for the pool surface and sanitation system. Apply the initial dose according to the chemical manufacturer's instructions. Record each treatment date and maintenance dose. Watch for discoloration, scale formation or recurring surface stains. Have the water professionally tested when the metal source or treatment need is uncertain. Frequently Asked Questions Is the Jack's Magic TK044 Sequest Test Kit discontinued? Yes. Jack's Magic has discontinued the TK044 Sequest Test Kit and the TK069 Sequest #1 tablets needed to perform the test. What replaced the Jack's Magic TK044? There is currently no confirmed complete direct replacement for the TK044. Pool owners and professionals may instead follow the sequestrant's maintenance schedule, test separately for dissolved metals and monitor the pool for recurring staining or scale. Can the TK019 Sequest #2 reagent be used by itself? No. The Sequest #2 reagent alone does not replace the complete test. The original procedure also required the discontinued Sequest #1 tablets and the proper titration equipment. Does a metal test measure the amount of sequestrant in the pool? No. A metal test measures metals such as iron or copper. It does not directly measure how much active sequestrant remains in the water. What is a pool sequestrant? A sequestrant is a water-treatment chemical that binds or controls dissolved metals and minerals to help reduce discoloration, scaling and surface staining. Sequestrants generally require periodic maintenance dosing because their effectiveness decreases over time. Can I use the Jack's Magic Stain ID Kit instead? The Stain ID Kit may help identify an appropriate treatment for an existing pool-surface stain, but it does not test the sequestrant level and is not a direct replacement for the TK044. How should I maintain sequestrant levels without the TK044? Follow the initial and maintenance dosage instructions for the specific sequestrant being used. Keep a written record of treatment dates, doses and pool volume, and periodically test the water for dissolved metals and other balance factors. Need help selecting the right metal or stain treatment? Contact Aqua Terra Backyard with your pool volume, surface type, sanitizer system, current water-test results and a description or photo of the staining concern. We can help narrow down the most appropriate treatment path. { "@context": "https://schema.org", "@type": "Product", "name": "Jack's Magic TK044 Sequest Test Kit", "description": "Discontinued Jack's Magic TK044 pool-water test kit formerly used to measure residual levels of compatible sequestering agents.
