Always add granules to water, never water to granules.\u003cbr\u003e3. Add slowly around the pool or spa with circulation running.\u003cbr\u003e4.

Hot tubs are small water volumes, so dose carefully, circulate well, and always test before bathing. Do not use the water until chlorine has returned to the safe range on your test kit and product label.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eIs this the same as Stabilised Chlorine Granules?\u003cbr\u003eNo. Stabilised Chlorine Granules are for routine sanitising and outdoor chlorine protection.

Do not mix the two products together in dry form or in the same dosing container.\u003c\/p\u003e\n\u003cp\u003eCan I swim straight after shocking?\u003cbr\u003eNo. Run filtration, allow the treatment to circulate, then retest.
