Product Description

Note: The usage amounts for Hykloron listed here are standard usage amounts. Free residual chlorine levels may be insufficient due to various factors such as weather, number of swimmers, and pool water cleanliness. Always measure free residual chlorine and replenish Hykloron if it is insufficient.

(1) Pool preparation before use
Dissolve 1-1.5g of granular Hykloron (Hykloron G) per 1m3 of pool water in a bucket. Distribute this solution evenly into the pool. This will bring the free residual chlorine level to 0.7-1.0mg/l, and the pool can be used immediately.

(2) Extended pool use
After adding the granular Hykloron, immediately add one 20g tablet of Hykloron (Tablet) - 20 per 5m3 of pool water, distributing it evenly. This will maintain free residual chlorine levels for approximately 3 hours.

(3) Continued pool use
Approximately 3 hours after the first tablet addition, add another 20g tablet of Hykloron (Tablet) - 20 per 5m3 of pool water, distributing it evenly. This will maintain free residual chlorine levels for an additional approximately 3 hours.
