Ive had my TF100 for a week and a half now. I tested everything last Thursday. My CH was 350..IF I did it right. I tested on Sunday (what I intend for my weekly tests) and my CH is 125. We did have a bunch of rain last week (probably 1.7 inches) and our pool is almost to the top right now. I can't imagine that the CH would go down so much. I also seem to have a similar issue w/ TA. Last week it was 90 and now it is 70.
I tested the chlorine today and it was at 2 (w CC at .5 -- as it has been for about the past week). Can I use the hth shock powder that has cal hypo in it? -- since I seem to need it (?)
Here are all my test numbers:
Also, in Pool Math, the goal says TA of 70-90+ . Then there is a space called Target. Do I put a number in there or did it calculate for me? I have now mixed myself up with it all. ( IF I am to put a number in, I think I will just go for a middle number from the goal numbers. )
