- Complete free of cyanuric acid (stabiliser) ~ no danger of over-stabilisation and green water due to the blocking of the action of chlorine
- Use it with any filter system, sand filters, glass filters or cartridge filters.
- Very safe product – the plastic casing prevents your fingers from coming into contact with the chemical product – the packaging has a special bright red safety lid that children cannot open.

Instructions for use for the HTH choor sticks:
For continuous maintenance of your pool, place 1 stick per 20 m3 of water in the skimmer per week.
ATTENTION: never use in combination with other products. May release dangerous gases (chlorine). This can happen, for example, if you mix ph min and chlorine or use it at the same time.

Add the HTH Chlorine Sticks to the pool skimmer so that the chlorine level remains between 1 and 2 mg/l. You can measure this chlorine value with test strips.
The average daily dose is between 150 and 200 gr. for 100 m3. Therefore, it depends on the occupancy of the pool, exposure to sunlight and pollution from slides, rapids, etc…
First adjust the pH value - then add HTH Chlorine Sticks.
It is important to check the pH regularly so that the pH remains between 7.0 and 7.2. When the pH value is too low or too high, the chlorine in your pool does not work as well to kill the bacteria.
The plastic cover remains around the HTH chlorine tablet
Around the HTH Chlorine sticks, 300g cylinders a plastic shell. This plastic foil may remain around the HTH chlorine cylinder. This plastic casing around the HTH chlorine tablets ensures that the chlorine dissolves slowly.
Due to this plastic casing, the tablets dissolve more slowly and the tablet releases its chlorine to the water more slowly. This protection also prevents your hands from coming into contact with the chemical product.
The HTH tubular tablets can NOT be used in a chlorine dispenser such as the Hayward chlorine dispenser or the Zodiac Nature 2 chlorine feeder. Only round pills of 200g fit in these systems.
The advantage of NOT stabilized HTH chlorine
With chlorine without stabilizer you avoid the risk of about stabilization and blocking of the action of your chlorine. This is because with common (cheaper) chlorine, cyanuric acid stabilizer has been added to the chlorine tablet. This is useful to prevent the chlorine from being broken down by the sun.
The disadvantage of this stabilizer is that it remains in the pool water. Because after a few swimming seasons and with little water change, this stabilizer accumulates. The result is that at a concentration higher than 70ppm the stabilizer blocks the effect of the chlorine.
This ensures that bacteria and algae are no longer properly destroyed. This creates green swimming pool water.

USEFUL INFORMATION:
Handy and best chlorine for the lowest price
Easy order and fast delivery. As mentioned, these sticks ensure that the cyanuric acid level does not rise, so that the chlorine continues to do its job.
Works fine
For several years I have only used the HTH chlorine sticks. In combination with maintaining the pH level with PHP minus, I have excellent clear water for an entire season. So far no other means have been needed for cloudy water or green deposits. My orders via Aquatechno are always correct and fast.
After overstabilizing the pool last year, I switched to this one and for now very satisfied with it.
