计算用泵填满泳池所要花费的时间。 填满你的游泳池。 等几小时后向水里放添加剂。

I'm interested in that, but I only have a few mins. Can you give me at most the first 500 characters of a detailed explanation in English about that?
You don't want to go to sleep and wake up with a lake in your backyard. Do a little bit of homework to avoid needing to damage-control in the end. Connect one or more garden hoses to available spigots and drop them into the side of the pool. Turn them on. If your pool was newly plastered for example, you probably want to tie on some socks to the spout of the hose and secure with a couple rubber bands. That way, the force of the water doesn't mess with the plaster. Water should not be expensive.
