The last time I checked my CYA levels was in March/April and it was at 50 and had been steady for the prior couple months. I checked it today and I can still barley see the dot with the cylinder completely full. I did 3 tests to be sure. I have only added a couple inches of water(plus rain) since the last test. I'm not sure where it went. I did do an AA treatment in May. I saw a thread saying that may lower CYA but it wasn't very conclusive. Could it be bad test chemicals? My CYA chemical is about 5 months old and has been stored indoors.
Temp 84
FC 5
CC 0
pH 7.6
TA 90
CH 310
CYA <30
Pool is using about 110 oz of 8.25 bleach a day to hold around 5-6 FC. We have a lot of trees so the pool does not get a lot of direct sun. Should this low CYA be a concern? If the test chemicals are bad I don't want screw up and put too much CYA in because I know how big a pain it is to get out. I had to do a 60% water change when we bought the house due to high CYA.
I have a bunch of pucks from the previous owner. I was thinking of throwing one of those in to see if I can get it back up on the scale at least. Thoughts?
