I guess all three of us where incorrect independently?
Being that each of us are pretty anal about testing and other confounding factors, it's not likely............
 
Surface movement/turnover/turbulances etc, flow rates etc all play a role, bubble size differences(CO2) etc. Also, biomass in the filter itself also plays a role.
 
The wet dry section needs to be sealed to the outside.
Various Overflow pipes can also reduce degassing/noise/gurggling.
 
The gas goes somewhere if the rate is truly the same.

You'll have to get in touch with the Canadian Food Inspection Agency. You
may need a phytosanitary certificate to get them over. A pretty labour
intensive and costly way to get clippings.

It's common practice to throw the waste pieces of gypsum drywall out the
windows of new homes as they being built. It collects around the perimeter
of the house. Then, rather than haul it off, it is frequently covered up by
a thin layer of topsoil and any landscaping. If you are having trouble
getting plants to grow near a recently built house, dig down and see if
there are pieces of old drywall buried under there. A little may be good,
too much is too much.

Well, when it is distinctly stratified and compressed, yes,
that can be a problem.

You don't want to know what else some guys do during house
construction, but if you are moving into a new home, it's a
good idea to flush the drains.

So far it looks like this might be the biggest year ever for Aquascaping Contest entries from countries outside of North America. 

Share the fun; show your work.
The AGA's 6th Annual International Aquascaping Contest is open.

The deadline for submissions to the AGA Aquascaping contest is September 15.

Entries are only $5 and for that half a sawbuck you can have your AGA entry automatically entered in the ADA (Aqua Design Amano) contest for free, a savings in time and shipping costs!

My neighbor was digging a pool and low and behold, guess what he found?

All the brick rubble from the neighborhood's construction had been
buried in his backyard. Tons of bricks, tons.....
