Bioguard® 5 Way Test Strips will test for sanitizer residual, pH, total alkalinity, and total hardness. These test strips will be the number one go to for most spas/pools for accuracy and quickness. We recommend testing your pool/spa weekly to make sure you stay on top of your chemical maintenance.
- Dip entire strip into water and remove immediately.
- Hold Strip level for 15 seconds (do not shake excess water from strip).
- Compare sanitizer residual, pH, Total Alkalinity and Total Hardness pads (in that order) to color chart on label.
