How a stop actually goes
Measure once
Work out the pool's volume properly and write it inside the equipment-pad lid. Every dose on this site starts from that number.
Test in order
Total alkalinity, then pH, then stabiliser, then chlorine. Correcting them out of order is why corrections do not hold.
Dose to the band
Each calculator draws the safe band and puts your reading on it, so you can see whether a correction is needed before you pour anything.
Four pillars

Water Chemistry
7 tools, 4 guides
Dose calculators and balance guides for chlorine, pH, alkalinity, stabiliser and salt — the readings a stop lives or dies by.

Equipment & Repair
3 tools, 5 guides
Sizing tools and repair walkthroughs for the pad: pump, filter, heater and salt cell — what fails, what it costs, what to replace.

Route & Pricing

Seasonal Care
3 tools, 5 guides
