Ok, first off I would like to say hi and thank you for this forum, I think this is going to help me with a lot of grief. So here is my current predicament. First off, since last year, my pool's chlorine levels no not increase, no matter what I do. My pool is 22,000 gallons in size, vinyl, IG. I have added lots of shock, as well as added bleach, and have not seen chlorine levels rise. One thing that I thought may have been part of the problems, was that my chlorinator had a lot of crud in it and wasn't circulating well. I changed that, but I am still having the problem as well as having issues now with ph.
Upon further research, I think I am getting an idea as to what my problem is. My CYA levels are high, very high in fact (probably due to abundant shock usage and the new chorlinator) I learned that the chlorine pills will drop my ph, so now that I have a new chlorinator and I was setting it to the max amount, I believe this was causing my ph to drop. So today I turned down the circulation level of the clorinator and am going to start adding borox as soon as I get home tonight to get ph under control. Also, my alkalinity is fine, thus why I am thinking about just adding borax.
so here are my questions,
1. Is what I am saying about ph and the chlorine tablets make sense?
2. What could be the reason my chorline levels are not rising, could it be that I have to much CYA in the pool? If so, how do I resolve this issue?
Finally, I have been using the pool strips to test my water, are they a good gauge for testing?
I am investing in the TF100 test kit and am looking forward to getting more control of my chemicals in my pool. Thanks again for any help.
