Pool Math: Volume, Dosage, and the Calculations Every Operator Needs

Master pH, chlorine, alkalinity, CYA, and hardness. The single most important skill for clear, safe water.

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.

Understand what every piece of your equipment pad does — and how to get more years out of it.

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 are not small pools. Higher temps, smaller volume, higher bather load — different rules.

CPO certification, tools of the trade, route building, and Florida licensing for pool techs.

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.
