- Floating Thermometer
Floating thermometers float on the surface of the swimming pool water, and are useful for monitoring swimming pool water temperature.
- Filter Cartridges
Filter cartridges are part of the swimming pool water filtration system, where pool water is passed through a cartridge, with any debris and dirt caught in the filter material, resulting in cleaner and clearer pool water.
- Filter Basket
A filter basket prevents large items and debris from entering the swimming pool pump, and should be checked often to keep pool water circulating efficiently.
- FAS DPD Test
The FAS DPD test is an enhancement to the regular DPD test, as it can directly measure free and total chlorine levels present in swimming pool water.
- Flocculant
Flocculants are chemicals designed to bind with contaminates or other chemicals in swimming pool water, allowing the combined result to be filtered or vacuumed from the pool water.
- Fading Endpoint
Fading endpoint is a situation occurring during testing of calcium hardness where the tested water sample turns purple instead of the expected blue color.
- Free Chlorine
Free chlorine sanitizes and oxidizes swimming pool water, keeping the water safe and clear for swimmers.
