Ask any traveling family: hotel pools are a serious draw–sometimes making the difference between an okay and a great stay, and a stay at your hotel versus another. Then, they’re a welcome refuge for adult travelers of all kinds, from business people seeking a quiet workout to couples looking for fun and relaxation.

For commercial and community pool operators, summer arrives all at once. High swimmer volumes, longer operating hours, higher water temperatures, and stricter public health scrutiny all put additional demand on your water chemistry program.

When stains appear on pool liners or plaster surfaces, they typically fall into three categories: metals, organic matter, or mineral buildup. For example, iron often leaves brown or rust-colored marks, copper can create blue-green discoloration, and calcium deposits show up as white or gray scaling. Determining the source is critical before beginning treatment. Treating a metal stain like organic...

A green pool is never a welcome sight, but especially not for commercial, public, or community facilities. Swimmers noticeit immediately, health inspectors ask questions, and sudden closures can disrupt your operations. In other words, it’s an issue that requires your immediate attention.

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,...
