I just thought I'd toss this around the newsgroup and see what kind of
opinions I get: What does everyone think about adding more aeration at
night
when the lights are off and plants have reversed their gas roles. I have
seen a few of my fish dwelling towards the water surface at night. I was
thinking about the possibility of adding a timed airstone for dark
periods.
I am concerned about fluctuating PH, but more about oxygenation for my
larger bodied fish.

Thanx for any help you can give!

Dave.
