Filter and dry the crystals. Chlorine is a sanitizer; Sand is a filter. You need chemicals with a sand filter because they require sanitization, phosphate removal, pH adjustments, and alkalinity alterations. Some pool owners who have a sand filter choose to use biguanide sanitizer, but this tends to stop the filter, which is why those who use this chemical need to change the sand more often.

Another reason so many people choose a sand filter over cartridge or earth filters is that it requires the least amount of maintenance. Use the context of the formation of saturated solutions of ammonium chloride to discuss the concepts of solution and saturation.8 Try this activity both qualitatively and quantitatively, introducing concentration and solubility calculations in later years. To effectively maintain an above ground pool with a sand filter, you will need a variety of pool chemicals. Cyanuric Acid: Dry or liquid chlorine stabilizer to protect chlorine from the sun.
