OK. My wife and I purchased a Intex Easy Set Pool (Round 18x48) about 3 summers ago. I set the pool up two summers in a row and fought the green water gremlin both years. We were using the shock, clorine, kick and cuss method to TRY and keep the water clear. Kicking and cussing seemed to work just as good as the clorine. So we put the pool up after the second year and I said I would never get it out again. But this year my wife and kids gave the puppy dog eyes and we are looking at putting the pool back up. We put air in the ring yesterday to see if it would still hold air and as much as I was hoping it would have a hole in it, it didn't. So now to my question. Is the shock/clorine the way to go or should I try something else. My wife's father had a pool a few years ago and swears that Baquacil was the way to go. I am also hearing alot about the saltwater systems. I would like to get everyones opinion on which way is the most economical, troublefree, and easiest to maintain. Any help is greatly appreciated. Because if the water turned green this year I am going to make sure it cannot EVER go up again.
