Just received the tf-100 test kit and here are the results (new pool, just filled and chemicals added three weeks ago):
CYA 40-50 (dot disappeared between these two numbers)
I guess the hardness is alittle low (but that shouldnt matter since the pool is vinyl liner??) Also with the low CH this is trowing off the SI as I am getting around -0.45 (but once again should this matter since there is a vinyl liner?)
Water is crystal clear
Located in Northcentral PA
Pool receives direct sunlight from about 8:00am - 6:00 p.m.
current water temp 82
Any other input or suggestions would be greatly appreciated. I have been doing my reading on this site for the last week and learning alot. I will be donating some $ here the near future (best site on the web).
