Chlorine and Pool Chemicals

Keeping pool water clean and safe depends on three things: disinfection, pH control, and algae prevention. In this category, you will find slow-dissolving chlorine tablets, granular shock chlorine, pH regulators, algaecides, and flocculants, in 5 kg and 25 kg formats, suitable for both private and community pools.

Slow Chlorine vs. Fast Chlorine: What Each One is For

Weekly Maintenance Routine

• 1 → Measure pH and free chlorine with a kit or test strips.
• 2 → Adjust pH to between 7.2 and 7.6.
• 3 → Replenish slow chlorine tablets to maintain 1–2 ppm free chlorine.
• 4 → Add maintenance algaecide and backwash the filter.
• 5 → If water is cloudy or green, apply shock chlorine at night and filter for 24 h.

Which format is most cost-effective for me?

• ✓ Above-ground pool or up to 30 m³: 5 kg format.
• ✓ Family in-ground pool (50–80 m³): 5 kg per season, or 25 kg if sharing with neighbors.
• ✓ Community, campsite, or hotel: the 25 kg format significantly reduces the cost per kilo.
• ✓ Chlorine tablets store well from one season to another if kept dry and sealed.

Pool chemicals should never be mixed dry. Consult the label and safety data sheet before use and store them out of reach of children. Do you have questions about your pool's dosage? Write to us at +34 621 20 71 54.
