I have a 15'x 4' Intex Metal Frame pool with the 1000gph filter. We bought the Saltwater Chlorinator because I didn't want to deal with all the chemicals with a regular pool. It was overwhelming to see all the things you had to buy and I didn't want to have to overthink my pool.
We have been using this for over a month and it is wonderful. I used the chart to put in the proper amount of salt, added the salt to fresh water and let it dissolve completely overnight. We got in the next day and played in the water for a bit to make sure it was well dissolved and mixed around and it was. We used Mortons Pool Salt which we found at our local home improvement store. I put in about 100lbs of salt. Ran it for the first time with no issues. Set up was easy once we read the instructions.
I have had no problems with error lights or anything. One time I had the low flow light, but I checked my filter and it was really dirty, cleaned it and it was off and running again. I look forward to my 93 reading every morning. I have my pump on a timer and the chlorinator comes on in the middle of the 6 hour pump cycle I run.
The only chemicals I have had to add was CY when I first started since we live where it is HOT and SUNNY. My chlorine was disappearing within a few hours when it was 110 degrees outside. Now it stays in a safe level until the next day. I usually run it for 3 hours a day. Haven't noticed a difference in my electric bill of any consequence. I also have to add acid when my pH is off. I check the chlorine and pH every morning when I go out to skim the pool. I have yet to shock the pool, crystal clear water, so haven't seen the need.
My kids love the salt water. The little one swims with her eyes open and they don't get red or irritated like they do at regular pools. I can taste the salt a bit in the water, but I don't mind. I am an ocean girl at heart and it isn't near the saltiness of the ocean.
I am very happy with my purchase. I hope to get at least 2 seasons out of this, we will see how it goes as time goes by and I will update if things change from how they are now.
