You need lots of things for a swimming pool. You can also go to POOL SUPPLIES stores to find more stuff for Swimming Pools. I'll give you some items, 1: pool cover 2: pool vacuum (sweeps on bottom of pool & cleans it) 3: net (a big net that catches dead bugs from the pool or leaves, mostly anything that falls on your pool, you can pick it up with the net and throw the stuff away) 4: (option) diving board or slide.
The most important things to have is the proper chemicals needed to keep the water safe. Other supplies you will need will be a water pump, filters, a vacuum and possibly lighting and heating.
