I have a small 10' x 30" Intex above ground pool. It holds just over 1000 gallons. I found the link for the "Super-simple pool chemical recipe for Intex pools: startup and routine care", on this forum, but it says it's for pools 12' or larger. I really like the simplicity of this system and would like to use it. Can I follow the steps for my smaller pool, and if so, how much would be a dose for my size pool?
