- so I purchased the intex 12'x30" round steel,frame pool along with a ground cloth, intex 1000gph pump and filter set ( I read the pump and filter that comes with the pool is junk), a intex Krystal klear saltwater system with copper ionization and (hopefully) all the necessary connectors. is this all I will need other than salt and water? also, for a pool this size (just under 1800 gallons) is the saltwater system a worthwhile purchase? will it actually save me that much in chemicals and hassle? and, last but not least, ground leveling. I have a pretty flat spot but there is a slight difference on one side. a little under 2 inches. I'm not trying to be lazy by skipping this step it's just that we rent this house and I'm hesitant to start digging up the yard. not sure how the landlord would feel about that, but then again, I'm not sure how they will feel about the pool! lol! I guess we'll find out. thanks!
