My appologies to the OP for being off topic, but his item caught my attention.

My SWG (Aquarite) recommends a CYA level of 60-80 (80 being ideal). So keeping CYA at 80, 5% of that results in a recommended FC level of 4. This is lower than recommended on the "Best Guess" chart (Best Guess chart says min FC of 5 at this CYA level).

Could you clarify this for me? If I can keep FC at 4, this will save some wear on my salt cell (which is a good thing considering the cost of replacement cells!).

Thanks.
