I have the same issue with chlorine level not rising. I don't plan to switch to liquid or other methods. I paid for a chlorinator and want it to work. Service crew apparently came out today and moved the valve adjuster to the top of the chlorinator and plugged the bottom one. Not real sure what that will accomplish.. Have you taken the line off to see if it's clear? If you turn the pump on no water enters after increasing the valve? They thought since I was on a lower speed most of the time it wasn't enough volume. Do you have a variable speed pump? I just put a puck in each skimmer this weekend for a bit. I'll call them tomorrow to see what they found, maybe it'll help you also.
