How many co2 bubbles per second for a Hagen Co2 unit?

Len, I think I did have a leak from the tubing to the lid. I pushed it down as hard as I could, and now I have a nice amount of tiny, tiny bubbles. Hopefully this will be effective enough for a 29 gal!

I'm going to let this run for a week before I test the ph and kh. I only have a ph test, so I'll have to invest in a kh test.
 
If you're going to get into plants you should invest in a few different kits, but check at your LFS for a master kit which would include pH,kH,gH,ammonia,nitrites, and nitrates. If you buy them all in one you'll save some bucks. kH is very important when using CO2 as it, combined with pH tells you how many ppm CO2 you have in your water among other things.

I don't know about a phone# for hagen but i have emailed them a few times with good results.Customer.Service@rchagen.com or send them this form(i have only used the form) http://www.hagen.com/canada/english/aquatic/contact.cfm

I have my hagen unit on a 15gal well within the range it says it should be used for. I have also tried many different times,following the directions exactly and still don't get much flow. I'm thinking i might jsut make my own yeast mix to put inside the container and see if taht works.
