Just joined the TFP site after reading a ton of great info and posts the last few weeks. I ordered a TF-100 and just completed all the tests to see where I'm at. I'm a little worried about the CH and CYA. We have very "hard" water here and have visible calcium build up on faucets in the home. I've gone with pool store chemicals since I've owned the pool (about 6 years).
17,000 gal gunite chlorine pool
Any help or suggestions would be great. I've read many posts about trapping rain water for the pool instead of filling from the City water supply so that may be something I have to look in to doing soon. I've have some visible signs of calcuim residue around my elevated spa waterfall and where some of the gunite meets the stone. I'm excited to get away from the pool store chemicals and learn more about the BBB method. Thank you!
