When it comes to selecting a pool sanitizer, there are a many different options. Incorrectly selecting a sanitizer can be extremely harmful to users and/or your pool, so the question should actually be “What is the best swimming pool sanitizer… for me?”
With safety, effectiveness, and budget in mind, finding the right sanitizer is actually a lot like shopping for a new car. While there are many factors to consider when selecting the right sanitizer for your pool, some of the more important ones are:
Indoor or Outdoor
- Stabilized sanitizers are intended only for outdoor use, while non-stabilized sanitizers are intended for indoor pools and are significantly less effective if used outdoors.
- Some sanitizers have by-products that can be harmful to breathe (“Lifeguard Lung”) and corrosive to indoor environments.
Bather Load and Type
- A zero-entry or activity pool will have a much higher bather load compared to a traditional lap pool. Therefore the activity pool requires a sanitizer that can keep up with the high demand, has a fast reaction time, yet is less expensive, since you will be going through more of it.
- An exercise, lap pool or hot tub where bathers will be sweating in the water will require a more potent sanitizer than compared to a leisure or lounging pool.
Availability and Delivery
- Depending on the location of your facility, some chemicals might have limited or no availability, or will need to be delivered from a distant location that will incur expensive delivery charges.
- Some chemicals require weekly delivery - can your members & facility accommodate this? One reason is that if direct access to the pool mechanical room is not available, chemicals will have to be carried though an occupied space, which is undesirable in most situations.
- Startup costs can range from just a couple hundred dollars to over $50,000 per system.
- Annual service, maintenance and energy costs should also be considered, as these can vary wildly.
- In a retrofit scenario, building and fire codes have specific requirements for handling and storing hazardous/flammable chemicals, so there may have to be special room(s) added to meet these requirements.
- In a new build scenario, square footage equals money, so even though the sanitizer system unit cost is relatively low, the construction & operational costs to house the system can add up to thousands of dollars.
- Always check with your local health department to verify the sanitizer is approved as either a primary or supplemental method of sanitation.
