I just received my TF Test Kit and my first test revealed a troubling result. First my pool has only had water in it for about 45 days.
Up until now I have been using a HTH 6 Way test kit and at first had good test numbers. As I had posted in another post, I started having trouble with my hardness test. After adding the indicator drops the water turned yellow. If I titrated it out anyway I got the same result (CH=280) as when the color was normal. I didn't worry too much about this situation because I knew mew new test kit was coming.
My first set of numbers using the TF Test Kit
TA 160 (I have been running my waterfall a lot to try and decrease this)
CYA 45 (I am slowly increasing this up to 75)
My TA had been slowly trending down from 120 down to 100 with the HTH. I didn't using both test kits on the same day.
My tap water has a CH of 30. I have heard of calcuim leeching out of the plaster. Should I be concerned about my CH level? Will it slowly decrease as water gets splashed out and the auto fill fills it back up. Should I do a partial water change?
