Thanks BCOrchidGuy, what I would be interested in is the ability to add oxygen to the water - Chaeto vs Skimmer.
Reason number two for me to run the Skimmer is its ability to oxygenate the water.
I just don't know if Chaeto alone is sufficient to add enough oxygen to the water. Would be great to hear if anyone has some more insight...
Thanks and Happy Reefing
