From what I've heard, KH

I wouldn't say that at all. It may be true with freshwater, but I don't do fw
so I don't have a clue there.
Stable alkalinity is good, but it can be too high or too low. Just because your alkalinity is stable doesn't mean it's good. If you have a alkalinity between 8-12 dKh
, then you should have stable pH... regardless of what the number is. While not accurate, you can think of alkalinity as a pH 'reserve'... more alkalinity will allow your pH to resist its normal tendency to drop.
But if your pH is below 7.8 or so (even if you alkalinity is stable), you might want to figure out why that is. If you're not seeing any ill effects, then it's probably better to just leave it alone. But there's an underlying reason why it's low, and if you CAN fix it, you probably should.
