My consecration is about .2 or lower. I am keeping it up manually
shocking the pool as needed. The Cyanurates are 100.

0.2 ppm free chlorine with 100 ppm cyanurates is useless.

You ought to check water in the output stream of the cell instead of your
bulk water. That concentration times the flow rate will tell if the cell
is producing the specified amount of chlorine per day regardless of what's
happening later to the chlorine in the pool.

If production is low, then test the wattage at the cell to diagnose the
cell versus the controller.

If you have a local dealer who sold you this or installed it, then you've
got to pressure them on their warranty of performance. Otherwise you've
got to fix it yourself.
