How many strips per tub?

50 strips per standard tub; 100 strip tubs available.

Will it read bromine?

Yes via DPD cross-reactivity; multiply chlorine reading by 2.25 for bromine.

Within 0.2 of a unit on pH, within 1 ppm on sanitiser, within 20 ppm on TA and hardness.

Use 3-in-1 daily for sanitiser and pH; use 6-in-1 weekly for the full picture.

12 months unopened; 6 months once opened.

Free chlorine, total chlorine, bromine, pH, total alkalinity, calcium hardness.

Hot tubs do not benefit from cyanuric acid stabiliser; CYA is a pool-only parameter.

Use liquid drop test for above 400 ppm; partial drain if too high.

Dose alkalinity increaser; retest after 4 hours.

6-in-1 vs photometer?

Strips are colour-match (semi-quantitative); photometer is digital (quantitative). Strips for daily, photometer for service log.

6-in-1 vs liquid kit?

Liquid kit gives finer accuracy on pH and TA; strips are far faster. Most owners use both.
