Fi-Clor Superfast Granules 450g

Arrived on time and as described

Does what it says in the tub!I would suggest that you only put a lid full each week to keep your hot tub ok!

Works great to super chlorinate. Glad we worked out how much to use instead of using the whole pot as instructed meaning we get 7 uses from this for our 12" pool

best on market , half a cap once a week for a hot tub keeps all well

it worked for me, delivered on time and worked as described

Does what it says it should and not scrimped on volume

Works as expected
