My husband and I inherited a pool when we bought our house last July, 2020. It is a 18ft above ground. I'm not complaining because I always wanted one. My husband could care less, so guess who is taking care of it? Totally new to the pool world. The local pool store seemed to be no help. I was always fighting cloudy water or algae. I even put in a new liner thinking that would help. It was just me being green (no pun intended) to the pool world. I used a Bioguard closing kit for the winter. I'm anxious to see how it is when we uncover it in a couple weeks. I've been looking for pool forums that does not have an incentive link for specific products. I just want straight honest answers. I think this board will help with what I need. I had planned to spend the extra money on Bioguard products because I thought maybe they were the best, however, reading on here may save me a little money. Thanks for letting me be a part of your pool world!
