OK, when you wrote this in the last post, I thought you might have
misspoken, but here you are repeating yourself. While plants _do_
respire, they do _not_ add to the CO2 levels in the tank (unless
they are rotting) They use _much more CO2 than they give off.
Likewise, while they do use some O2, they give off _much_ greater
amounts during photosynthesis.

If a planted tank is properly set up, there will be almost no
"cycle" to be seen. Certainly not one of any consequence.

That is good advice.
