I have a 12,000-gallon saltwater pool in NJ which has a Pentair IC30 SWG. I purchased the house in August 2020, at the time the Owner told me the pool was converted to salt water back in 2017. Therefore, my Pentair IC30 SWG is around 6 years old. The SWG has been working fine, last season (2022) I kept it at 40% and never had an issue. Reading TPF forums, many say that a cell will last 5-7 years. Question is, do I wait for it to fail since I am within that 5-7 year timeframe, or just replace it now before it fails? If the recommendation is to replace it, should I go with an IChlor 20 or 40? My pool guy is suggesting I wait, and when it's time to replace it, go with the IChlor 20. He said the IChlor 40 is way oversized and the SWG will need to run at a very low output (10-20%) which can be bad for the cell. What are your thoughts???
