Pool Water Chemistry: Ideal Levels Chart + Guide
The ideal pool chemistry levels — pH 7.4–7.6, free chlorine 1–3 ppm, alkalinity 80–120, CYA 30–50, calcium 200–400 — plus how to test and fix each one in Florida's climate.
Cloudy water? Green pool? Confused by your salt cell or test strips? We wrote 219+ plain-English guides covering everything Florida pool owners actually run into — water chemistry, troubleshooting, cleaning, equipment, salt systems, and the South Florida realities (yes, iguanas) the manufacturers won't tell you about. Written by our CPO-certified techs from real route experience. No email gates. No fluff.

Skim, brush, vacuum, and service your filter. A disciplined weekly routine prevents 90% of pool problems.
Cloudy water, algae, stains, foaming — every problem has a cause. Here's how pros diagnose and fix them.
Pool pumps, filters, heaters, salt systems, and cleaners explained — what each part does, why it fails, and how to get more years out of your equipment pad.
Florida pool safety standards, VGB drain covers, fencing code, and the emergency response every operator should know.
Hurricane prep, year-round operation, hard water, screen enclosures, and the challenges unique to Florida.
Spas aren't small pools — higher temps, smaller volume, and heavier bather load change every rule. Spa chemistry, heating, sanitizer, and common repairs, done right.
How to build a pool-service career in Florida — CPO certification, the tools that pay for themselves, route building, pricing, and getting licensed step by step.
Pool volume, chemical dosage, and breakpoint math. The numbers behind every safe, correctly-dosed pool.
The HOCl vs. OCl equilibrium, CT values, and disinfection by-products. The science every CPO-level operator needs to know.
Cryptosporidium, fecal incident response, and the RWIs that close pools. The CDC-compliant playbook.
Turnover rate, total dynamic head, cavitation, suction entrapment, and the physics of making water move through a pool.
Filter media rate, micron ratings, sand vs. cartridge vs. DE, and what filters can and can't actually remove.
Chemical feeders, ORP/pH controllers, pool heating, indoor air quality, and the electrical safety every commercial operator needs.
The MAHC, ANSI/APSP/ICC standards, ADA accessibility, and the federal alphabet soup of pool regulation.
Every Florida pool license explained in plain English — what each one lets you do, how to get it step-by-step, and which counties make it harder.
New plaster has a 30-day chemistry window. Do it right and the surface lasts 15–20 years. Do it wrong and you're looking at etching, scaling, and a warranty void.
Required daily logs, incident reporting, operator duty of care, and the documentation that defends you in court.
