Not so small inflatable type pool approx. 500 gallons. 8ft round X 21in high. I live in SE Alaska and the nearest store that sells pool chemical equipment is on another island and is somewhat difficult to travel to. Is there some recipe of bleach or whatever to keep some sort of pool cleanliness before or after the kids would like to use it? Thanks in advance!

I clean and manage the swimming pool at home without the help of a professional cleaner but I am at lost as to how and where is the best place to put a container of clorine at home.At the moment ,I store it in a shed but the intensity of the clorine is slowly melting all of the metals components in and around the shed.I am also worried that it could cause harm to my plants and animals that walks past the shed
