And what is the CYA level in ppm?

It sounds as though you need to add cyanor to the pool water ... it can be done with chlorine Puch, because these also contain cyanor .... but you've probably solved the problem ...? :?:

Could you share the readings of all of it that you got on your test?

Pool owners that switch to a chlorine generator do not want to add tri-chlor or other forms of chlorine as it defeats the purpose. It is recommended to just use standard Cyanuric acid which is available in both a dry, and liquid form. If you post your CYA levels along with the shallow depth + deep depth / 2 x L x W, we will be able to help you out.
