Ben:

With the water clear and seemingly under control, do I still need to run my filter 24-7 as we reduce the TA by holding down the pH?

It seems like the "aeration" associated with running the system will tend to drive the pH up unnecessarily and, if that is not helpful, I'd like to return to a more standard "daytime" pump & filter operating schedule (like 12 hours per day).

Thanks.

Lee
