I have a Jandy Aquapure 700. Recently my pool has turned a nasty shade of green even though I ran my pump longer than normal. I get a service code of 125 and 194. Then when I push the salinity button to silence the alarm, I get 123. I called a pool tech and he told me that I'd probably need to replace the cell, but he also looked like he was confused and didn't even check the voltage. He called Jandy and of course they told him to replace the cell. Is there anything else it could be before I shell out $450 and replump my pump? I already gave the cell an acid wash.
