| I made this and it was very easy. I just have yet to have someone tell me how to determine how much co2 is in the water. I know the pH will go down as carbonic acid builds up, but mine is now off the chart yellow. Till I learn how to maintain a non toxic amount I'm keeping an eye on my fish.
I guess if they start looking sick I'll turn it down or off. |

| | That was incredibly helpful. The guys at plantgeek forums were no help at all!!! That calculator gave me a figure of about 38 ppm co2 in the water, a bit higher than 30 ppm, but not off the charts as I was fearing. |
