In an effort to get my CYA up to 80, I used the pool calculator and added enough to get there (a little less, or so I thought). Now, my CYA is over 100 if my eyeballs are working properly. I did all this to try to maintain a higher FC value in my 95 degrees days with full sun.
How bad is it? I used the TF-100, and am not totally sure when the black dot disappears, but my wife has agreed with me so far. Not sure if one of the other tests may have a better method for measuring this accurately. I do not trust any result the pool stores tell me b/c on a recent visit my buddy and I split my water sample, and got completely different results. So...I don't know who to trust
The water does look clear, and I have just continued to add bleach to keep the Cl at a decent level, and from other posts this seems normal
