Brand: Jack's Magic    SKU: JMSTAINID

Product Overview

The Jack's Magic Stain Identification Kit is a four-test diagnostic kit used to determine which Jack's Magic treatment is most likely to remove a swimming-pool surface stain. Iron, copper, cobalt, organic material, scale, and other deposits can create similar-looking discoloration, so choosing a stain remover by color alone can waste product or complicate the condition. This kit lets the pool owner or service professional test the stained area before purchasing a full treatment quantity.

Each test is applied topically to the stain according to the enclosed instructions. The stain's response indicates the matching Jack's Magic treatment family and helps establish the correct next step. Water temperature matters: Jack's Magic recommends testing when the pool water is at least approximately 65 to 70 degrees Fahrenheit so the reactions can be observed more reliably. The kit is intended for diagnosis, not for treating an entire pool.

Before testing, confirm that the discoloration is on the pool surface rather than suspended debris, algae, or a shadow. Follow the current kit instructions, record which test creates the clearest response, and use the identified treatment's complete preparation, dosage, and rebalancing procedure.

Key Features

  • Includes four topical stain-identification tests
  • Helps distinguish between treatment categories before full dosing
  • Reduces guesswork when stains have a similar appearance
  • Supports selection of the correct Jack's Magic stain solution
  • Compact diagnostic kit for pool owners and service professionals

Common Uses

  • Identifying an unknown pool-surface stain
  • Confirming whether Stain Solution #1 or another treatment is appropriate
  • Testing before purchasing a full-pool chemical dose
  • Troubleshooting stains on common pool surfaces

Testing and Compatibility Notes

Use only as directed on an actual stained area. For more dependable results, the pool water should generally be at least 65 to 70°F. The kit identifies a treatment path but does not replace the label, dosage calculation, or water-preparation instructions for the selected full treatment.

Frequently Asked Questions

Does the kit remove the stain?

No. It contains small diagnostic tests used to identify the treatment most likely to work.

Why does water temperature matter?

Cold water can slow the test response and make the result harder to interpret. Testing at approximately 65 to 70°F or warmer is recommended.

Can stain color alone identify the metal?

Not reliably. Different causes can produce similar colors, which is why a topical test is recommended.

Why Buy the Jack's Magic Stain ID Kit from Big Frog Supply?

This kit helps prevent buying a full-size stain chemical before the condition is identified. Big Frog Supply carries the matching Jack's Magic treatments, chlorine reducer, and maintenance sequestrants, so the diagnostic result can be followed with the correct product rather than a generic stain-removal guess.
