Hi,
I have a new to me old IG plaster pool (house is 55 years old). Within a couple of weeks of moving in, I ended up with a bright green swamp and lots of pool store advice (and products!). After finding this site, I now have my sparkling clear water back and couldn't be happier.
My question is my cya level. Before my slam, it was way over 100 (by pool store testing and by my own). After slamming I re-measured it (twice because I thought it was not right) and came up with 75 (both times). Now, 4 weeks later, I thought I would check it again. I have not drained the pool, and the only water loss has been back-flushing and evaporation. I have been having to run fresh water into it for 20 to 30 minutes and day ( have not yet measured flow rate). And so this morning my cya level is 40! Does this seem right? Where did it go? If it is right then I guess my chlorine level is too high. I did not recheck since this used up the last of my reagent and I need to replenish.
Other results:
fc = 8
tc = 8.5
cc = 0.5
ph = 7.6
ta = 120
cya = 40(?)
Thanks for all your help,
Gwen
