Information from VersaChlor:
Unlike trichlor tablets, VersaChlor tablets contain no cyanuric acid.  Users are free to add as much or as little stabilizer as they may need. That means with VersaChlor tablets there is no CYA buildup to slow the action of chlorine in cleaning and disinfecting the water.  Also, VersaChlor tablets release chlorine at a predictable rate. Together, these tablet features make it easy to sustain proper chlorination and help prevent illness-causing bacteria from forming in pools and spas.
VersaChlor tablets are specially engineered using a proprietary process and are put through extensive quality control so they won’t soften and clog the system like other brands of tablets.
VersaChlor tablets are five times more concentrated than liquid bleach. The tablets come packaged in a 37.5-lb. plastic pail, allowing for an easy to store and handle container compared to heavy, bulky bleach drums.
