It is safe to swim after adding hydrochloric acid to swimming pool. but in a small quantity like for a pool just a liter of dil. HCl (0.1N) . But if you use conc. HCl , then there may be chances of skin burn or blisters etc. to the skin.
It mainly depends on concentration. and amount of water is added.
DO NOT ADD conc. HCL to the water. There will the chances of bursting.
I would wait for at least 2-hours afterwards. Keep in mind it takes 1 full hour to cycle around the entire radius of your pool once you add a chemical to your water
It will mix very quickly so you can swim immediately. However what are you putting sulphuric acid in your pool for you should be using hydrochloric or mercuric acid
Read the label, but usually it is safe. Pool Masters
Shock your pool at sundown and you can swim in it the next morning.
maybe if you like to hurt yourself
Any time you like calcium is harmless
you should have your pool tested just to be on the safe side.
Most metal control products are safe to add with no harm to bathers
yes it is safe
My pool store said wait 5 hours, but it probably depends on the amount and concentration (liquid or powder).
yes it is safe
Yes, you are supposed to add it while there is water in the pool. Add with filter running near a return line. Add it slowly and if possible, brush the pool to help mix the acid. You can swim within 30-60 minutes.
yes.. it has a low pH ... acid rain... so you need to add pH plus.
