Pond C02 levels?
There is a segment on CO2 at http://www.akca.org/ search for CO2 and it will
take you to a page on water quality. It gives no numbers, but describes the effect on pH and how to control CO2 levels. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "JGW" wrote in message ... Does anybody have a sense of what an acceptable range for pond water C02 levels is? I checked all the pond water chemistry web pages I could find and couldn't find any guidelines. Thanks.

CO2 is not that much a problem: add extra aeration and it's done with. Or
plants will use it during the day (but make it during the night) - so air stones or venturies or water falls or ANYthing that will increase oxygenation is OK and will off gas the CO2. The gas you need to be worried about is *hydrogen sulfide*: this will KILL your fish. - it's the stuff that smells like rotten eggs when you disturb pockets of it, like when you clean the pond. What's the save level for that? ZERO Lee "JGW" wrote in message ... Does anybody have a sense of what an acceptable range for pond water C02 levels is?

Joan _______________ I wouldnt worry about it. There's no way to push the Co2 level up high enough to hurt the fish without Co2 injection. Co2 injection is used by aquarium people for planted tanks. It would def help out the submerged plants in koi ponds but you'd need one heck of a co2 system and you'd want to keep water movement down to a minimum. Most people move the water around a lot in koi ponds to get more o2 in the water because they generally overstock fish. Water will contain the same amount of co2 as the air. Any water movement will bubble off any "extra" co2 that's added to a system (just like shaking a can of pop). Sam |

Thanks. A fish person told me to check the CO2 in my pond because some of my fish were dying, and she thought it might be a good nonspecific indicator of some kind of toxicity.

Okay, thanks. We have a waterfall and a good air bubbler. Hope that is doing the job. I'll be on the lookout (or smell-out) for hydrogen sulfide. I know, that's hard to miss.
