Bubbles per minute is a relative measure that depends on several variables,
so a bubble count that works for one person may not work for
another. Instead, test the CO2 levels (pH + KH) at the current rate of
60bpm and then use the bubble count to adjust up or down as needed. Give
things time to stabilize before readjusting. To make sure CO2 is good
throughout the photoperiod, test once about the time lights come on and
again about the time they go off.
Micro Bubbler tip: If you find that large bubbles begin escaping from the
stone around the rubber ends, seal them off with silicone or epoxy (best
done by disassembling the stone).
