  • Form: granules
  • Recommended use: control algae and bacteria in swimming pools

This granular chlorine acts quickly to kill algae and bacteria on contact and can be used for routine daily maintenance or as a shock treatment.

Worth every cent

Did a lot of comparison shopping before buying here and I have no regrets. Best price I found anywhere and delivery was fast — 3 days to Melbourne. Product feels genuinely premium, not cheap at all. Packaging was solid too, box arrived in perfect shape. Will be back for more.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.
