Thank you kindly! I'm sorry, I'm not sure what method the dealer used. I will lower the CYA by draining/refilling partially and will go from there. Earlier in this thread I had read that shocking is not required when using the bleach method. Could you elaborate on that? Thank you once again for all the helpful info!

These are the results of testing done by dealer: Free Chlorine: 0.89ppm Total Chlorine: 3.12ppm Combined Chlorine: 2.23ppm pH 8.2 Alkalinity 122ppm Adjusted Alkalinity 98ppm Calcium Hardness 158ppm CYA 79ppm I have balanced the pH down to 7.4 and the alkalinity has come down with it to about 50ppm. (Tested with Strips) Water has been clear throughout, but I think I must not have added enough bleach after every use. The Original Clorox here in Canada does not state the %Chlorine on the bottle, which is not helpful. Thank you for your thoughts!

Switched to the bleach method, and have really liked the ease of use so far. Just got the water tested at the pool store: Free Chlorine 0.9ppm, Combined Chlorine 2.2ppm. Would it make sense to shock with bleach up to 22ppm FC?
