Hi, I'm so glad I found this forum. I started in 2011 with a blue 10'x30" intex, in 2012, I decided to upgrade to an 16' x 48" intex ultra frame. Today, I finally decided to pull the trigger and get a 21' x 52" Morada pool. I'm so glad I did but really nervous about it. I think I may actually post the spot I had the old intex and show progress as the new pool is being installed. Since I'm new to pool ownership and still learning how to keep everything balanced and sanatized, I'm sure I will be here alot.
