You know what? I had planned on putting that into my disclaimer part....I
am using Tetra test kits. Sorry about that.

OK, if it is a small enough swing that it doesn't show up on a Tetra test
kit wouldn't it be safe to assume that the swing is insignificant for what I
am trying to do...getting the CO2 to a reasonable level for the plants to
use?

PS thank you for all the responses to this post. I have learned so much
from people like Roger Miller, George Booth, and Scott. This list is great
and has a ton of nice and helpful people in it. Sometimes it goes WAY over
my head but when I need things to be explained better usually someone
does....again thank you.
