TCCA 50% (20g tablets) contains 50% available chlorine and dissolves slowly. It is ideal for use in a floater or skimmer to provide continuous chlorine release, making it highly cost-effective for daily maintenance. TCCA 90% has a higher concentration, which is better suited for shocking or treating pools with severe algae problems, but it comes at a higher price. For regular daily use, TCCA 50% tablets offer much better value.

Yes, it is highly necessary. TCCA has a low pH (acidic), so adding it will slightly lower your pool's pH. You should always maintain a pH level of 7.2-7.6. If the pH drops below 7.0, add Soda Ash to adjust it. If the pH goes above 7.8, the chlorine's effectiveness can decrease by up to 80%. Therefore, maintaining the proper pH is just as important as adding chlorine.

For a standard medium-sized home pool (40-60 cubic meters) with normal usage, 10 kg should last about 3 to 5 months, using approximately 12 tablets every 35 days. This duration can vary depending on weather conditions, bather load, and natural chlorine loss.

Because TCCA 50% dissolves slowly, you can generally swim as usual without waiting long. However, you should always verify that the Free Chlorine level does not exceed 3.0 ppm before entering the water. If you have performed a shock treatment (adding a large dose), you should wait 4-8 hours and test the water first.

In the case of a green pool caused by algae, you should first use TCCA 90% powder or Calcium Hypochlorite for a shock treatment because they act much faster. After that, you can switch back to TCCA 50% tablets for continuous maintenance. Using TCCA 50% tablets alone may not be sufficient to resolve a severe algae bloom.
