I just registered for Trouble Free Pool. I am trying to get use to the website. I bought a 18' round pool in April and was talked into using the Baquacil system. I have been dissatisfied from the start. I have had 3 pools in my life and all up to this one have been chlorine based. I really don't know why I changed, my bad. I have found help on this website on converting and I want to become a TFP supporter. I will do that in the near future. Looking forward to any support I can get on the conversion I will do next year when opening the pool up.
