Okay, thanks for the information. I'll let you know what the outcome is.

OK, here is what happened. Previously my Jandy 1400 salt system was getting 120 & 121 codes, had lots of buildup in the cell, and I was getting green looking algae on the pool walls. I am not a pool guy and had not been trained on the system even when it was installed several years ago. The pool company said to clean the cell with the 4-1 (water/acid) solution and if that didn’t work, I should buy a new system. I proceeded to submerge the cell in a bucket and let sit for 20 to 25 minutes then blow out with a hose. I could see pieces of the buildup coming out but nothing changed as far as performance. I was getting the CELL ON light and assumed it was trying to produce chlorine, just not enough to make a difference in the pool. I was almost to the point of buying a new cell and made a final attempt to clean the cell. This time I did not let the cell sit in the solution, instead, I prepared 3 ½ to 1 (water acid) and poured the solution through it, (gloves and glasses on) over and over again. This action seemed to remove more of the buildup, then blew it out with a water hose. I did this two times on consecutive days. ALAS, I have a sparkling blue pool, no algae and it’s been two weeks now. I’m still monitoring it closely but so far so good. I now know I need to clean the cell every few months to keep the buildup away.
Thanks for your help Pool Clown.
