Insta-TEST® Copper Test Strips 25 per Bottle
Product Overview
A proven choice for pool techs who need to monitor mineral levels without the rush of rapidly fading test results.
Curated by Simplified Pools for its reliability, the LaMotte Insta-TEST COPPER (model 2991-G-12) is a standard specification for monitoring mineral-treated water. This specific formula allows for stable color development, giving you adequate time to match the strip to the 0-3.0 ppm scale on the bottle label. In our experience, these strips reliably handle the precision required to prevent copper-based staining in plaster and vinyl pools.
Benefits & What Makes It Different
0-3.0 ppm Measurement
Provides a wide enough range to detect both trace mineral levels and high concentrations that could lead to surface staining.
G-12 Stable Formula
Engineered to maintain color integrity on the strip, ensuring you have enough time to accurately compare results against the reference chart.
25 Strips per Bottle
A convenient quantity for homeowners to perform weekly testing throughout a standard swim season without the strips expiring prematurely.
Compatibility
- Safe for plaster, vinyl, and fiberglass surfaces
- Compatible with salt water and traditional chlorine systems
- Designed for use with all major mineral ionizer brands
When To Use This
Pro Tip
If your copper levels exceed 1.0 ppm, we suggest using a metal sequestering agent immediately to prevent the copper from precipitating out and staining your pool's finish.
Common Questions & Instructions
Why are my copper levels rising even if I do not use a mineral system?
High copper levels can result from low pH water corroding your pool heater's copper heat exchanger or from using certain copper-based algaecides for green pool recovery.
How do I get the most accurate reading with Insta-TEST Copper strips?
Dip the strip into the water for two seconds, remove it with the pads facing up, and wait fifteen seconds before comparing to the 0-3.0 ppm scale on the bottle.
Will these strips help prevent green hair and pool staining?
By monitoring levels and keeping them below 0.5 ppm (unless specified by your ionizer), you can reliably prevent the oxidation that causes green hair and black stains.
