Hi, does the board (Aquarite, pre 2008) show any kind of indication or just produce less and less?
My past units since 2004 never showed any signs after conistently 3 1/2 years and i had always found out the hard way by doing all kind of checking before getting a new one. This current one has only been a little 2 yrs and is doing the same. Last night i superchlorinated it and this morning, after 10hrs, it only raised fc from about .5-1 range to 1-2 range. Last week i took the cell for testing at the store and it passed. It seemd they only test to see if it work electronically, not if it produce decent amount of fc. The rep from Hayward also said if all indicator lights show normal it means the cell works. Can the computer tell if the cell is working?
Also, my pool has been high salt up to 4000 in the past year (didnt want to drain due to the drought), would that affect the cell's life.
The rep from Hayward also asked me to check for phosphate and nitrate. Pool store couln't do nitrate and my phosphate was zero (i doudt if the guy knew what he was doing). Do these chemical affect the cell's life? I was told phosphate is not important and stopped using them.
