Ok, just replaced spider gasket in filter. Was really bad and was losing lots of water. Seems to have fixed that issue. Test water and here's what I get:
I added 112 ounces of 6% bleach, and 45 ounces of muriatic acid. No real improvement after 24 hours. Test chlorine again, basically 0 again. Add another 112 ounces of bleach. No improvement. I believe the filter is functioning correctly, but could the spider gasket not be working correctly? Water seems to be flowing as it should, and I am not losing water anymore.
The pool calculator says to also add 293 ounces of calcium chloride. I did not. Is this why I am not seeing any improvement?
Thanks to everyone on here. This site has been a huge help.
