Do I use the flow jet or my flow controller.The last I used the flow controller I had very high tds in the foot well.I have tried to flush in my customers pool, but they preferred me to use there RO. I had this problem dealing with my membrane before.Does anyone think my TDS was to high to flush or should I just get a carbon block replacement. All adverse( remarks) will be appreciated, but some will just pee me off. I will not discuss my Ipoff training today.Thank you adversity.
