I just wanted to say THANK YOU for all the advise I have found here. I started the BBB method three weeks ago with the purchase of a T-100 kit. I have been slowly adjusting everything and today i walked out to test the pool and found the water was so clear i appeared to be empty (if that makes sence) I just very very clear!! I have borax strips on order and once they arrive I will start working the borax up towards the 50 ppm mark. Thank you all once again for sharing your knowldge with us all!!!!
