Hey, I am new here! My husband and I have been battling with our pool the past 2 summers. After throwing away tons of money, we have recently decided to go with the BBB method. We have been doing research, and from what we have read it should be the way to go. We have an in ground vinyl pool, he says it holds about 25,000 gallons. We purchased our test kit last week...according to that, our CYA was off the charts. We have been gradually draining and refilling a little at a time. It is FINALLY just now reading right about 100. I am getting frustrated because of how slow this process is. I just now took a look at the pool calculator and found out we will need to replace 60% of our pool.... UGH! As if this isn't costing enough as it is, ha! Any advice...maybe other suggestions? Encouragement??
