CYA 100
Hello all. This is my first post on the forum, although I have been lurking for a while now.
Due to the previous owners of our house, and partially because of my own ignorance before I found this forum, I have been draining and refilling my pool to correct CYA levels that were at 190. Needless to say, after learning about the CYA problem, I am no longer using dichlor or trichlor and am now converting the the BBB method. After two partial drains and refills, I now have the CYA down to 100. I'm gonna try to manage that for the rest of the summer and then do another partial drain in the fall to bring it down more.
After the drain was when I switched from dichlor to bleach, so only been using the bleach for a couple of days now. Good news is that last night I did an over-night chlorine loss test and my FC levels held perfectly. And, there is no combined chlorine, and the pool is sparkling. So it looks like I've passed those three criteria. I am keeping the FC between 9 and 12 as recommended by the charts here.
Here is my first question though: I checked the FC this morning and it was 10. Then, this evening I checked and it was 8. So, it appears that my daily chlorine loss is 2. So I added 40 oz of liquid chlorine to bring it back to ten. So that is about a third of a gallon. Is this normal? It just seems like so much! At this rate I will be going through two gallons per week. If this is normal, I'm gonna buy some stock in whoever makes this liquid bleach! Our pool is exposed to full sun all day, so maybe it is normal. I just didn't expect to have to use so much every day.
Second question is the TA. It was totally fine, holding at about 125 before I switched to the liquid bleach. Now, in just a couple of days it has jumped to 170??? This just seems really strange. And the PH is fine, and has been holding steady. I checked my test twice. I don't know if this is related, but when I did the test, it is supposed to turn from green to red. Well before turning to red, it became clear, then with one or two more drops it turned red. I had no idea where to call the drops; at the clear change or at the red change. Any thoughts on what is going on with this? Should I be concerned about it?
Thanks for any help and thanks for a great website.
