Hy-Clor granular pool chlorine is a 4kg calcium hypochlorite treatment that delivers fast-acting, economical daily sanitising to control algae and bacteria in your swimming pool, with the larger pack suiting bigger pools or frequent dosing.
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. As an unstabilised chlorine, it does not contain stabiliser, so add a separate stabiliser if your pool needs it.
