Since your water is already at a pH of 7.6, it seems to me that the
driftwood is not having any effect.

Bubbling means the CO2 is simply leaving your tank. Dissolved CO2 would not
bubble. So you do need a reactor. But you can make one of your own. See any
of the simple designs in the FAQ. You'll find them through the Krib Web
site. Mainly they consist of nothing more than an upright tube capped at
both ends. The CO2 is fed through the bottom and water is dripped down the
top or flows through holes in the side of the bottom half (the bottom half
because gas rises and holes in the top half would let the CO2 "bubble"
away.)
