And you say a pH of 7.5. Numbers don't get much better than that. I'd try to run FC at 6 or 7 with that much CYA, but that's me.

I think TDS is total BS in real-world conditions. But it sounds impressive (like acid demand). With number like yours, and NO discernable problems, go swim and ignore TDS.
