Application Instructions

Commissioning freshly filled new hot tubs or ones left drained for a period of
time: Following latest guidance, a commissioning dose of 50mg/l free chlorine
maintained for a minimum of one hour is recommended.
Floating Dispenser: Add tablet(s) to the (trichlor) floating dispenser and adjust
the flow mechanism at the base of the dispenser to obtain the free chlorine range of 3 โ 5mg/l. Alternatively, leave the flow setting on the dispenser, but vary the number of tablets inside.
Note: The dispenser should be removed while the hot tub is in use.
Chlorine Feeder: Add chlorine tablets to the dispenser and follow the instruction manual on flow regulation.
Note: It is recommended that you periodically (e.g., weekly or after prolonged hot tub use) shock dose your hot tub with AquaSPArkle Spa Fusion, Spa Non Chlorine
hock or Spa Rapid Shock.
Use this Aquasparkle 1kg pack of Multifunctional Chlorine Tablets to disinfect and sanitise your hot tub / spa.
Chlorine tablets have a high pH value, so they don’t cause acid damage to hot tub equipment or seals.
This makes maintaining the sanitizer level in your spa very straightforward. When using a floating dispenser remember to remove it from the spa and place it on a non-bleachable surface while people are bathing.
