We have a 30,000-gallon saltwater and fiberglass pool. I am looking to learn from the group and offer advice if I have any, LOL. I take my water tests to Leslie's but after 3 years of doing that I am ready to do the tests and additives myself. We keep the pool open year-round and have remarkable success in it staying clear and I must thank Leslie's for the advice. So, now that I want to do the tests myself I thought what better time to join a community forum.
