Exact chemical doses. No more guessing.
Your tech enters today's readings. PoolSurf pulls pool volume, water chemistry, and product concentration, then tells them exactly how much liquid chlorine, muriatic acid, or stabilizer to pour. Rounded to the nearest cup. LSI forecast built in.

Everything you get with Automatic Dosage Calculator
Built by people who've actually run the truck. Every benefit below came from a pool service owner who asked for it.
Dose, not a guess
Readings in, recommended dose out — in the exact units you buy (oz, cups, lbs, tablets). Every pool dosed right, by every tech, on day one.
Pool-volume aware
Calculations use each pool's actual gallons. A 12,000-gal spa and a 32,000-gal pool get different doses automatically. No math, no mistakes.
Every chemistry parameter
Free chlorine, combined, pH, total alkalinity, CYA, calcium hardness, salt, phosphates, TDS. Whatever's out of range, PoolSurf recommends the fix.
Uses your product, your concentration
Pulls the product from inventory — 10% liquid chlorine, 31.45% muriatic, dichlor, trichlor tabs. Each product's concentration feeds the dose. No generic "add chlorine."
Rounded to what fits in a jug
Apply in ounces, buy in gallons. Rounding rules make sure you don't ask a tech to pour 14.7 oz — it'll say one pint.
LSI scale, live
Langelier Saturation Index plots as readings come in. Balanced, corrosive, or scaling — techs see it on the bar before they pour. Etched plaster and stained tile become somebody else's problem.
Inventory decrements automatically
When the tech pours the recommended dose, truck stock drops and the cost attributes to that pool. Usage and reorder handle themselves.
Safety guardrails
Caps on single doses for pH-up, acid, and shock. If a calculation asks for too much, the app flags it and splits the dose across visits instead of burning the pool.
The difference, in plain English
Running a pool company before and after Automatic Dosage Calculator.
The old chem bag
- Techs eyeballing "a couple scoops" of shock, hoping it's close
- Same dose on every pool, no matter the volume
- Generic recommendations that don't match the product on the truck
- Over-acidified pools and etched plaster two weeks later
- No tie between what was poured and what the invoice says
- Training new techs on a laminated chart nobody reads
With PoolSurf
- Every pour sized to this pool, this reading, this product
- LSI scale turns green before the tech walks away
- Truck stock decrements and cost lands on the visit
- New techs nail chemistry day one, no chart needed
- Acid doses capped so nobody torches a plaster finish
- Owners audit the whole chemistry program from one report
How it works
Three steps from "we should try this" to running it across the whole crew.
Tech enters readings
FC, pH, alkalinity, CYA, calcium — straight from their phone. One tap per field, no math.
PoolSurf calculates the dose
Uses the pool's gallons, the selected product and concentration, and the delta to target. Rounded to the nearest practical unit.
Tech pours and logs
Recommended dose shows on the mobile app. Tech pours, confirms, and inventory decrements. LSI updates live on the scale.
Frequently asked questions
The stuff pool service owners usually ask about Automatic Dosage Calculator.
Does it know my specific chlorine concentration?
Yes. Each product in your price book has its concentration and sales units. Liquid at 10%, 12.5%, dichlor at 56%, trichlor at 90% — the dose math uses the real number, not an assumption.
What about salt pools?
Salt, cell output, and hardness all factor in. Recommendations can say "raise cell output to 70%" or "add 2 bags of salt" depending on the reading and equipment.
Can I set my own target ranges?
Per pool, per package. Commercial pools, saltwater spas, and residential maintenance can each have their own targets. The dose math respects whichever package is on the pool.
Does it protect against overdoses?
Built-in caps on single doses for pH-down (acid), pH-up, and shock. If a reading is wildly off, the calculator splits the correction across multiple visits instead of recommending a dangerous pour.
What about LSI?
Langelier Saturation Index is calculated live from pH, alkalinity, calcium, cyanurate, and temperature. The scale shows corrosive, balanced, or scaling — techs can course-correct before they finish the visit.
