Alright - well I run the pump for about 6 hours a day with the SWCG set to 60% - keeps the FC at 4. I am going to leave it there.

I tested my own CYA on Saturday - it was less than 20 - Poolstore had it at 10 last Monday.... I am guessing the pool builder didn't add any like they said they were going to - I am going to take another sample to the pool store today to verify and then add additional stablizer to get to the 60-80ppm range.

Thanks for the advice!
