Hey guys, I'm anticipating finishing my 18x33 above ground pool tomorrow and filling it the next day... I'm just curious if you could advise me as to how much bleach, borax and baking powder to buy upfront. I don't want to underbuy and have to go back to walmart 3-4 times.

I'll be filling it with culinary water.... I believe it came out to right around 15000 gallons.

Also, is there a decent water test kit I can buy from walmart or leslies, (or somewhere similar) to use temporarily? I need to order a kit from the site, but want something to get me by in the time it'll take to ship it.
