Pool winterizing product. Prevents water from going stale, the formation of algae, and lime deposits during the winter season. Before applying the product, the pool must be treated with chlorine according to the instructions. The product contains 10-12% didecyl dimethyl ammonium chloride, 3.5% copper sulfate, and 1-3% hydrochloric acid.
After the summer season ends (when the temperature permanently drops below 15 °C), carry out the so-called superchlorination with CTX-200 / GR. The next day, dose CTX-550 into the pool (5 liters / 100 m3 of water). The water pH should then be adjusted to 7.2 - 7.6. Pour the required amount of CTX-550 evenly over the surface of the pool. For the product to work effectively, it is advisable to keep the filtration system running for a certain period of time. During application or afterwards, it is not permitted to use the winterized pool (due to the very high chlorine content in the water). If weather conditions allow, it is recommended to repeat the treatment of the pool water with CTX-550 in the middle of the winter season.
Use biocidal products safely. Always read the label and product information before use.
