    Chrona, Have you checked your pH leaving it in the tank running from the airstone?
    If bubble wands dissipate co2, why couldn't you just leave it go as is?
    Bubble wands dissipate CO2, but only it they are bubbling air bubbles. If they are bubbling CO2, then the amount of CO2 lost as a result of it is much less than the amount of CO2 added

    I'll get back to you on the pH story. I'm still waiting on my new light fixture to arrive before I start up my CO2 reactor. However, from my research, a CO2 injections that add 20ppm (ideal) will lower your pH by a little less than 0.8. (this will vary depending on how many plants you have, how fast they take in the CO2, and how fast your particular reactor puts CO2 into the tank)

    Heres a good link
    http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm

    Oh, and leaving the CO2 airstone in the tank will result in a lower pH at night, because plants don't use it at night. You can however, turn on an air pump then, because both fish and plants use oxygen at night.

    Great site. Been there 100 times but never saw that page. Now, a few years in chemistry I will figure it all out. LOL Thanks as this will give me some sort of godliness.

    I also understand now about the bubble wands. Makes perfect sense now.

    oops, i would have thought you would have heard of one of those since it seems you have a lot of aquarium experience. but i will say that the "I am a female" line you used is pretty lame though especially since your trying to fabricate a co2 system.

    LOL I know how to do stuff. Just don't know the names of what I'm using.

    This planting business is new to me so along with that comes the figuring out of plants, substract, CO2, yadda, yadda. I will get it figured out yet with all the help I've gotten here.

    figuring it out shouldn't be that hard, it's just trying to comprehend all of the physics of how it works may tend to be a littls challenging

    Yeah, I did extremely well in all of my chem classes, but there are so many variables when it comes to CO2 injection that I'm still not quite sure I understand it completely.

    ah hell, just pump it in until stuff starts going bad then just back it off a little.




    just kidding.

    I think with an airstone diffuser and DYI (low pressure) reactors, the levels of CO2 won't reach the maximum though, so I'll probably just do what you said lol.

    remember that more c02 in your tank does not mean less oxygen. for my DIY system this is what I use:
    gallon container (ocean spray cranberry juice)
    6 cups of sugar
    1 tsp yeast (room temp)
    air stone, letting into my powerhead.

    I change it every two weeks, whether it needs it or not, just to keep the supply steady. there's some calcium in my substrate, so it kind of balances the ph.

    The fish are happy, the plants are happy, and i'm happy!

    If you're concerned about ph fluctuations at night, you can always add an airstone for regular air at night. This will displace some of the co2 and add the needed oxygen for both the plants and fish, since the plants use oxygen to grow at night.
