Try adding Baking soda with SeaChem's equilibrium to yield a GH/KH 4 to 5.
Have your pH at 6.6 to 6.8. You'll find it much more stable than CaCO3 and
much faster/easier to hit what range you want. You can use CaCO3 if you
wish but it does take awhile for it to dissolve. No Mg either. A couple of
hours or less compared to a couple of days. Also added are some other traces
and macro's like K+, Mg in SeaChem's EQ.

CO2 is good after the GH/KH level off but what of the time in between when
you add it and when it finally stabilizes? And the hassle? I'd use baking
soda and something separate for GH. Many folks in the SF bay have similar
tap waters(little to no GH/KH) and they have used this as I have on a few
folk's tanks in the area over a long time period (years now) with excellent
results. Bottom line is that you'll have a nicer tank using this method and
an easier time doing it.
