So, We are getting ready to set up a 15x30 AG. Brand new liner. At our last house we had an AG that had been put underground... Such a bad idea in so many ways!!! This time we are setting pool on the ground where it belongs and building the deck around the pool and hot tub. Very exciting! My question is what should I do to open the pool? Last time around I took a water sample to pool store and guess what.... yep... it needed tons of stuff. Apparently our water is very hard. I am going to order the suggested test kit and I am reading your forums like crazy! Any other advice? I love the tips! I am a couple weeks away from adding water, but I figured it wouldn't hurt to get set up here so when the questions arise I will already have a login etc. Thanks!!!!
