Accurately calculating the volume of a pool is the foundation for every chemical decision you make as a pool operator. If you don’t know how much water is in the pool, you can’t reliably calculate chlorine, pH adjusters, stabilizer, or shock. And when dosing is off, even by a little, water quality and safety problems follow.

Swimming pool management is complex. Beyond ensuring a fantastic guest experience, there are chemistry, safety, compliance, and risk considerations that keep commercial operators on their toes. The Certified Pool Operator (CPO) certification helps ensure you or someone on your staff is adequately prepared and trained to handle these complexities, as well as to guide your operations. It's the ...

Mustard algae in pool environments can be one of the most frustrating water quality issues commercial and public pool operators face, often returning even when pool chemistry appears to be under control. It can show up when everything else looks “within range,” then keep coming back—clinging to walls, spreading to equipment, and resisting normal sanitation routines.

Black algae is one of the most persistent and costly issues a commercial or public pool can face. For operators responsible for maintaining safe, code-compliant pools, the appearance of dark, stubborn, spot-like growths on plaster or concrete surfaces is a sign that water chemistry, sanitation, or maintenance routines need immediate attention.

For commercial and public pool operators, maintaining proper chlorine levels is a core part of guest safety, pool reputation, and a regulatory requirement. Whether you manage a municipal facility, a hotel pool, a fitness center, or a multi-pool aquatic complex, the chemistry behind your water management program directly affects bather health, equipment lifespan, operational costs, and your...

Saltwater pools are often misunderstood as “low maintenance,” but commercial and public facilities know better. While salt chlorine generators (SCGs) produce a steady chlorine residual, which can improve chlorine consistency, they do not eliminate the need for shocking. In high-bather, regulated environments, shock treatment remains a critical operational tool for restoring water quality,...

Summary: Commercial and public pools rely on chlorine for safe water, but each chlorine type—stabilized solids, liquid chlorine, cal hypo, and salt-chlorination systems—has distinct pros, cons, and operational impacts. Choosing the right one affects water quality, maintenance demands, cost, staff workload, and guest experience. This guide explains how each option performs in high-use aquatic...
