Know exactly how much chlorine to add. The Pool Chemical Balancer takes your current water test results — pH, free chlorine, alkalinity, cyanuric acid, calcium hardness — and tells you the exact amount of each chemical to add for your pool size. Liquid chlorine, cal-hypo, dichlor, trichlor, muriatic acid, soda ash, sodium bicarb. Exact ounces and pounds. No more guessing, no more overdosing, no more chasing chemistry all day. Langelier Saturation Index built in. Enter your numbers, see instantly if your water is balanced, corrosive, or scaling. Green means balanced. Red means fix it now. Turnover Rate Calculator shows how long your filtration system takes to cycle the entire pool volume. Input pool gallons and pump flow rate. See if you meet the 6-hour health code requirement or if you need to investigate flow issues. Daily Pool Operations Log replaces your paper logbook. Tap to enter water test results, bather load, chemicals added, weather conditions. History stored for 6 months — matching health department record retention requirements. Export to CSV for inspections. This is the tool you open every morning before the pool opens. 700+ practice questions covering everything on the CPO exam: water chemistry and balance (pH, chlorine, alkalinity, CYA, calcium hardness, LSI), disinfection and sanitization (breakpoint chlorination, shocking, fecal incident response), filtration systems (sand, DE, cartridge, backwashing), pool and spa calculations (volume, dosage, turnover, flow rate), health and safety regulations (record keeping, pool closures, bather load), mechanical systems (pumps, heaters, valves, skimmers), water quality testing (DPD vs OTO, testing frequency), facility operations (opening/closing, winterizing, emergency procedures), spa and hot tub operations (temperature limits, drain frequency, higher sanitizer levels), codes and standards (VGB Act, ADA, barrier requirements). Every question includes a detailed explanation. Calculation questions show step-by-step math so you learn the method, not just the answer. Full mock exam: 50 questions, 2-hour timer, open-book format matching the real CPO exam. Category-weighted. Pass/fail result with breakdown showing exactly which topics need more work.
