If only I lived out in San Jose! I hope SVAS embraces the talk.. you dont need any extra pictures do you?

Hope you're doing well Tom (despite the current state of APD).. good to see you around here again.

Well, here's the interesting thing, the marine plants do better with lots of mist from the skimmers and powerheads, this is just air, so FW plants should have a similar increase in growth using CO2 mist.

You can find better growth in places below rapids and pearling of mosses etc.

Increasing gas exchange is a two way street also, the mist may export more O2 and bring in more CO2.

Marine folks can watch those bubbles float all over for very long peroids of time.

That's why the planted marine tanks do so well with a skimmer and aeration vs none.

Air does not dissolve very rapidly into the water.
Maybe all those skimmer bubbles are N2 gas huh?

hehe

I confess, this had certainly crossed my mind. I was considering offering it up as food for thought on APD, but decided it just wasnt a good idea at the moment. Its had enough flaming topics in the last month.. adding more fuel didnt seem like a great idea. When I have an amazing tank to show, then maybe I'll try.

Turning on the venturi aerators on the powerheads certainly does seem to lessen my need to add back alkalinity. I would think that would be at least a little evidence that its doing something for the available carbon in the tank.
