Seems that starting with one is good for acclimation reasons. the PH will go up pretty quickly! I acclimated mine by putting an airlin T in place full open and closing it a bit every day.
If you skimmer pulls a lot of air you should consider buying in bulk (5 gallons at airgas) as you might go through the media quicker than most.
for the double, you can share the same reactor, just make sure it can handle the flow. that way you only have one reactor to monitor and replace media in.
