The Jacuzzi Chemical Dispense is an optional attachment that installs easily to the center filter cap on all J300 and J400 spas. Control the rate of tablet dissolve by a sliding fitting inside the dispenser.
Note: Chlorine tablets are damaging to hot tubs and may void your warranty. It is recommended that this product not be used in hot tubs. It is safer and better to use granules (How much chlorine do I use?)
