Pool Chemistry Log & Dosing Chart Pack: Printable Log Sheets, Dosing Charts for 5,000-40,000 Gallons

What it does

Twice-a-day chlorine and pH check sheets (the CDC's testing advice for home pools) and full-test log sheets keep a season of readings together. Dosing charts for chlorine, alkalinity, calcium hardness, stabilizer and salt give you the amount for 5,000 to 40,000 gallons, and a one-time table turns them into your own pool's amounts. A target-range page says who set each number (CDC for home pools, or the public-pool code it borrows from), and a safety page gives each chlorine label's own re-entry line for swimming. Every dose is computed from published constants; the solid-chemical, acid and salt figures agree with PHTA's dosing guide, and where a published figure differs (liquid chlorine, for one) the pack says why. Estimates for planning, not professional advice: your product label always wins.

What's included

Log sheets

• 2 twice-a-day check sheets, two weeks to a page (FC and pH, twice a day, plus chemicals added); print as many as your season needs
• 6 landscape full-test log sheets (84 test lines): FC, CC, pH, TA, CH, CYA, salt, temperature, chemicals added, notes, with the ranges printed above each sheet
• Season summary: monthly low/high per reading, out-of-range count, chemical spend and quantity tracker
• Pool profile and product label record (strength, basis, specific gravity), with the 11.9% vs 15% jug-label trap explained

Dosing charts

• Order of adjustment (Indiana Dept. of Health sequence), what trichlor, dichlor and cal hypo add to the water, and a per-1-ppm table with a column to fill in for your own pool
• 4 pages of dosing charts: liquid chlorine, cal hypo, dichlor, trichlor; baking soda; muriatic and dry acid; calcium chloride; cyanuric acid; salt; water-replacement percentages for high stabilizer
• "Work Out a Dose" worksheet with the formula, constants and a worked example, for any product or strength

Reference

• Volume worksheet: rectangle, round, oval (two published formulas, and why they differ) and kidney
• Target-range page with the source of each figure, and the lowest everyday free chlorine for any stabilizer level (CDC minimum or CYA / 45)
• Opening and closing checklists (order for the water only, not freeze protection)

Safety

• Chemical safety page: never-mix rules and handling quotes from CDC, EPA and the MAHC unchanged; calcium hypochlorite vs trichlor/dichlor incompatibility; each chlorine label's re-entry limit; sources and where published sources disagree

Who it's for

Owners of residential above-ground or in-ground pools (chlorine or salt) who test their own water and want a paper log and a trustworthy lookup, including new owners who don't yet trust a rule-of-thumb from a pool store.
