[F] CO2 - "mineral water"

One more reason AGAINST the use of mineral water is mentioned in "The Optimum
Aquarium" book by  Horst & Kipper, page 84:

"Furthermore, the concentration of salts which are present in greater or
lesser quantities in mineral waters, have an uncontrolled negative effect on
aquarium water."

In other words, mineral waters also contain salts (not just NaCl) besides 
just water and CO2. These salts might affect the aquarium water quality.

CO2 from Club Soda????

Not recommending this, but thought you might be interested in the
following story told to me by a long-time aquarist. It seems that the
benefits of adding CO2 to a plant tank have been known for years and
people have always searched for cheaper ways of doing it. This fellow
told me that he used to buy a soda syphon (which used to be used many
years ago for producing tonic water) and squirt it straight into the
tank. He emptied a full canister at once and saw his pH drop quickly. He
said that he got excellent plant growth !!

He was quick to point out that he wouldn't do this nowadays as you can
achieve the same effect cheaply with yeast.
