Spa chemicals

[josaphine32]

Hi,
I treated my self the other day to a lay z spa, I am just abit concerned about the chemicals, Ive read the owners manual back to front and still cant get an answer, Can someone please tell me If when you add the chemicals should you have the pump on or off?. also is it ok to leave the cover on the spa while chemicals have been added plus is it ok to add the chemicals individualy but at the same time?. and most importantly, How long do you have to waite before you can get back into the water?.
I bought chlorine granuals and have read the instructions to just tip it in if spa is over 20 degrees (which it is ) and they all sank,

I just dont fancy chemical poisoning at the moment. Thanks
