IMO, Tetra errs too far in the direction of caution. I have yet
to see a CO2 supplemented tank that does _not_ exceed Tetra's
"safe" zone. For that matter, according to them, none of the
tanks I tested were in the "too low" zone. Use the pH/KH chart...
it's more useful.

Because of my moderately hard water, to keep the pH where I want
it (about 6.8) I run my tanks at about 28 mg/l CO2. I've been
doing this for years, and have seen no adverse effects in my fish,
including sensitve species like Discus and Rummynose Tetras (some
of my Rummynoses are 5+ years old)
One caveat... As long as CO2 levels are kept reasonable, what's
much more important than the absolute value is that any changes be
made slowly and as infrequently as possible. I would not
recommend working toward the higher end of the safe range with a
yeast reactor... the output is just not steady enough.

The one Mark spoke of _is_ winter hardy, and a major nuisance in
many areas. Not all Milfoils are, however. It depends which one
