My husband and I just purchased a home with an in ground pool in early May. We used a service until the end of July. August has been rough! We have had our water tested and done everything the local pool stores have told us to do...spending a fortune, to still have cloudy water with high CYA & Phosphates. We have a friend that is a member of TFP and introduced us. We are draining some water out of the pool today and refilling to hopefully lower the level and get started with the TFP way of doing things!
