Pearling After a Water Change

been ages. Found any interesting local aquatic plants lately?):
"...So I'm wondering why nobody has rigged up a "free CO2" thing by letting
a water supply go into a 50' hose to pressureze then releasing it into the
tank 1 - 4 times a day...."

Could it have anyhting to do with the fact that, along with the CO2, a lot
of N2 would get forced into the water by that method and might cause
problems for the fish as it comes out of solution, along the line of "the
bends" that divers face if they ignore decompression breaks following a deep
dive?

Just a thought.....
