I have been adding CYA directly to the skimmer without issues but I have to run the pump 12-24 hours as recommended. Yesterday I added 2lbs. of CYA in a sock and suspended it just in front of the waterfall (under the water). I am trying this method simply so that I don't have to run the pump that long when 5-6 hours of runtime seems adequate for my pool. The CYA appears to be dissolving very very slow unless I squeeze the sock and large amount of cloudy white water emerges.
My question is, is it okay to use this method and not have the pump running 24/7 ? Is it okay to squeeze the sock when the pump is not running ?
