The easiest way to keep your KH (and therefore your pH) at baseline (tap/well) levels is to do sufficient water changes. That way, the readings won't drop and therefore won't need to be snapped back into line. This, of course, assumes that your tap/well water is of satisfactory quality/quantity in the first place. If that's not the case, then baking soda can be used to boost the KH. So like Kathy asked, what are your baseline (tap/well) readings for pH, KH & GH?

I used to get mild fluctuations until I was convinced (I believe by Don) to change my way of thinking and now with 10% daily water changes my ph is solid as a rock.

Just one of the benefits....
