What is the PH of your tap water
(after you let it sit several hours?) Compare that PH reading to your
tank
PH and you should see a difference.

I use RO/DI water and the pH of that is pretty low. The test kit reads
6.0
but I have a hard time beleiving it.
I guess all I can really go on is KH which that test kit is at work.
I'll
have to get another one...

Mort,

Your tank PH *should* be lower than your RO reading if your CO2 injection
is
working properly... UNLESS you have something in the tank that is raising
your KH.

I just finished testing the water.

KH is at 0 (is that good) pH is lower than 6.0 (so it would seem) as the
sample turned a dark yellow. I decided to test my GH while I was at it and
that turned out to be 3-4.

I havent had time to check out Chucks chart but I will do that ASAP.
