Two years ago we bought a 18 x 48 intex easy set pool and we sunk tons of money into chemicals trying to keep our water from being green and it was just impossible and we are novices to pools and the upkeep, so whatever they told us to do at the pool store after testing our water we did, and still we had nothing but green water. So we didn't mess with it last year and we decided this year to set it up and order the intex krystal clear saltwater system, and now we are waiting for it to be delivered and my question is can I go ahead and add 120 lbs. of pool salt to the pool water so that it can start dissolving while I wait for the arrival of the saltwater system???
