2. Maintain free chlorine residuals for spas within the range 3 ? 5mg/l (ppm).? For swimming pools it should be 1 – 3mg/l (ppm). Freshly filled spas require an initial shock or start up dose of chlorine: 50mg/l (ppm) for 1 hour or 20mg/l (ppm) for 2 hours.
3. This product may be applied directly to pools or spas where temperatures exceed 20? degrees C.

I was using the tablets on my pool and they are just not quick enough when you have a whole family jumping in and out all day. The graduals are so much better, easy to use and fast working

If you have animals and cant get rid of tge urine smells they create, simply add a small amount 2 tea spoon to a hot bucket of water and let it dissolve tye swill the area. It will remove 100 of the smell. Also add a little to mop bucket when mopping the floor incase the dogs have walked any in.
