Test Strips: Pros, Cons, and When to Use Them
Use strips as a fast screening tool, not as the final authority for expensive dosing or algae-remediation decisions.

Most important limitation
CDC notes that test strips are less accurate than a DPD test kit. That makes strips acceptable for quick checks, but weak for FC/CYA decisions, Overnight Chlorine Loss Test (OCLT), or SLAM work.
Use strips for triage, not precision
A strip can answer 'does this look roughly in range?' faster than a drop test, but it should not pretend to be a high-resolution instrument.
Know when strips are not enough
Some decisions require better resolution than a color pad can provide.
- → If the result would trigger draining, acid washing, or a major chlorine dose, retest with a stronger method first.
Read strips consistently
Technique problems can make a rough method even rougher.
- → When the strip is ambiguous, record a range and retest with liquid chemistry instead of pretending you have precision.
Upgrade path
The question is not whether strips are useless. The question is whether they are strong enough for the decision in front of you.
