Beyond sanitizer and pH chemicals, facilities use specialty products to keep water clear and surfaces safe: clarifiers and enzymes, phosphate removers, metal and scale inhibitors, stain treatments, and cleaners for electrolytic cells. Site disinfection equipment addresses decks, locker rooms, and touch surfaces rather than the water itself.
FreyTech supplies E-Z Clor and Jack's Magic pool chemicals. Our approach is to fix the root cause first (filtration, circulation, control) and use specialty chemicals deliberately, with storage, compatibility, and safety data sheets handled properly.

Selection considerations
Confirm compatibility with the sanitizer program, filter media, and any UV or ozone.
Manual, feeder, or metering-pump application changes handling and consistency.
Segregated storage and current safety data sheets for every product on site.

Chemical delivery is how sanitizer and pH chemicals physically reach the water once the controller calls for them.
Filtration removes the particles that chemistry cannot.
New York requires manual testing of pH and free and total chlorine at the beginning, during, and end of each swimming period with a DPD kit and fresh reagents (10 NYCRR 6-1.11).
