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?
