The right dose, every time.
Clearwater turns a water test into exact amounts for your pool or hot tub — and tells you when to test next.
Chlorine targets that follow your stabiliser
3 ppm is fine at CYA 30 and dangerous at CYA 80. Most apps give one fixed number. That is why the strip says “ok” and the water still turns green.
Water balance, not just clarity
Clear water can still be eating your plaster, grout and salt cell. Clearwater shows the balance index and what to change first.
Doses that account for buffering
Acid dose depends on alkalinity — at TA 120 you need twice as much as at TA 60. We calculate it, and flag what each product adds behind your back.
A plan that reads the weather
Sun burns chlorine, rain dilutes everything. Clearwater projects your chlorine forward and warns you before it drops below the minimum.
Safety built in
Never-mix warnings, split doses when a correction is too big, and a clear answer to “can we swim?”
Pool and hot tub
Different targets, different rhythms. Small volumes get smaller, safer doses.
