pressurized co2 questions

well, after having been in the hobby for almost a year now, i finally got my pressurized co2 system setup this morning before class. on my 20g Long, I have a 2.5lb cylinder and a JBJ regulator with solenoid, needle valve, and bubble counter. I set it up at about 1-2 a second seeming to have recalled reading that amount on the forums. The co2 is dispursed via a powerhead and venturi nozzle (left over from the red sea system, soon to be replaced with a diffuser).

much to my surprise, when i finally got home this evening and checked the co2 levels my readings worried me a lot.

PH - 6.5-6.7 (that is the range of the three readings, i can't ever be sure on those little "match the color" tests"
KH - 9.0

given the ph range, that means (using chucks calculator) that my co2 is anywhere from 54-88ppm. I seem to remember reading about some people keeping their co2 levels up in the high 40's low 50's, but 80's?

my fish aren't pale, and they aren't breathing heavy or anything. they are actually looking in really good health. whats the deal?

i've used the charts and my reading are off the chart. But that's just me. My fish are fine and my plants are growing. But I keep my PH stable at 6.4 and everything seems to stay in stasis. If things don't looks right then I think you need the opinion of some of the high tech test readers on this forum. I fly a little more by the seat of my pants, but /I have all the handy dandy gadgets to test for problems should I feel the need to reassure myself. try lowering the bubbles to 1 per second or 1 per 5 seconds...and see if things balance out better for ya. but Keep an eye on your fish and plants...they will tell you when things are wrong.

good luck.

Fish, plant's, algae, never lie, test kit's do, as you see, they take some getting use to on how to use/read them, use the test kit's to know your source water,
Most folk's goof up alot because they spend way to much energy on trying to read number's, ask Scolly then do some study on how C02 effect's pH, based on KH.
Learning to read the fish, plant's algae is just as important, once you master the light/C02, there won't be any algae to really read any more.
