Pond C02 levels?
 

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.

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.

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

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).

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.

Oh that's good to know. Thanks. Hmmm. So why did I buy that CO2
kit???
