So glad I found this website and to own my TF100 test kit. Been a few weeks and the pool is looking great. Headed to the pool store a couple days back because I needed to raise my CYA. Took a sample in for grins and got a "Wow, your number are great". Told the worker I'm using liquid chlorine and he thought I was crazy. Wanted me to buy a huge bucket of tabs because of the simplicity. I told him I test and add chorine daily and he said to me, "that's like mowing your lawn every day". I wish I could mow in under two minutes. . You still got to feed your dog even on days you don't play with them.
