Benefits & What Makes It Different
0 to 3.0 ppm Total Range

Desiccant-Lined Bottle (G-12)
The 2991-G-12 packaging seals out ambient humidity to protect the 25 dry reagent pads from moisture damage between weekly tests.

- Reads total copper levels in residential and commercial pools and spas
When To Use This
Pro Tip
Never touch the chemical pad with bare fingers before dipping; natural skin oils and trace lotion residue will contaminate the reagent and produce false copper readings.
Common Questions & Instructions
How often should I test pool water with copper test strips?
Test every one to two weeks if you run an ionizer or mineral system, or immediately after applying copper-based algaecides. Typical pool owners go through one to two bottles of 25 strips per season to keep residual copper within the safe 0.2 to 0.4 ppm target and below 3.0 ppm.
Where should I collect water when using LaMotte 2991-G-12 test strips?
Dip a single strip elbow-deep (about 18 inches below the surface) in an open area of the pool, away from return jet streams and skimmer throats, to ensure you sample thoroughly mixed water rather than concentrated chemical output.
How can I tell if my copper test strips have gone bad?
Inspect the dry pads before use; if pads show discoloration, blotching, or clumping while still in the vial, the reagent has degraded from moisture exposure. Toss the compromised bottle and replace it to avoid inaccurate copper readings.
