We have a 15 foot round/ 4 feet deep, steel wall above ground pool. It's nice for the kids, and I get in when I am hot from yard work.
Our pump & filter set up is not what came with the pool. We have a large sand filter and a stronger pump made to keep a 24 foot in ground pool clean
makes my job easier. I only run the filter about an hour a day during summer.........turn it on and leave it. About once a week I 'vacuum' the pool floor, which is a vacuum head attached to a hose that goes to the skimmer.
About every few days I have a little test kit to check PH level & Chlorine levels..........you fill the little thing with pool water and add drops of the tester fluid. You check it against the color chart to be sure it is in the "safe" zone. EASY.
We use a Chlorine with built in Clarifier..........we have never needed anything else to keep water clean, clear, and safe. The stuff we use comes from Meijers and costs 20.00.........we usually go through 3 cannisters per summer.
We only add water when it gets splashed out or evaporates too low for the skimmer (little box that the water flows into for filter) And for the winter we drain water below skimmer, add lots of Chlorine, and cover till spring.
This is all the info I can think of right now.
