You need
- 5 g tablets2
- 10 g tablets1
- 20 g tablets—
Let the tablet dissolve fully and wait at least 30 minutes before using the water. Re-treat when fresh, untreated water is added.
🧪Sodium Hypochlorite Dilution Calculator
Make a ready-to-use disinfectant solution of the right strength from Cleansol Sodium Hypochlorite.
Mix
- Sodium hypochlorite20 ml
- Water980 ml
- Total1 L
Add the hypochlorite to the water (not water to the hypochlorite) in a plastic bucket. Make fresh solution every day – it loses strength. Never mix with acids, toilet cleaners or ammonia.
🏊Swimming Pool Chlorine Calculator
Work out your pool volume and how much chlorine raises free chlorine to the level you want (ideal: 1–3 ppm).
Length × width × average depth
Your pool
- TCCA 90 granules / tablets167 g
- Sodium hypochlorite 10–12%1.5 L
Use one product, not both. Dissolve granules in a bucket of pool water first (or use a floater for tablets), add in the evening with the pump running, and re-test after 4–6 hours. Swim only when free chlorine is back to 1–3 ppm.
