If you put in a gallon or less per 10,000 gallons of water don't worry about it; but wait 4 hours after running filter before entering. Bleach is chlorine which helps the pool rid bacteria, although chlorine powder or tablets is preferable.
Give it a couple days, it will dissipate.
Sure but it is not the same strength as pool chlorine. It can also contain metals that can stain you pool surface.
2gallons per 10k of water
None. That is extremely unhealthy to your child.
Not if you let the kids into it. Better to drain it, use bleach to clean and kill the algi, and then rinse well.
Get out of the room, and open the doors and windows until you cannot smell either chlorine or ammonia.
Yes but you also need chlorine stabilizer (CYA) or the chlorine will be destroyed by sunlight in a very short time or you need to add the bleach in doses thoughout the day to maintain the chlorine level. Bleach is the same as liquid pool chlorine but at a lower concentration.
how much chlorine do I put for a 1,718 gallon pool
You should remove the antifreeze with a shop vac if possible, antifreeze will not hurt the water, but is just one more thing in the water that you do not need to be there.
As long as the baby did not put their hand in their mouth, it is fine. You should wash your babies hand as soon as you can.
I do. Use half as much. Pool chlorine is 12.5% sodium hypochlorite Laundry bleach that I use is 6% sodium hypochlorite. Sometimes I dilute the pool chlorine by one part water to one part pool chlorine and use it just like regular laundry bleach.
Yes it will help keep things under control and make it easier when you startit up again.
