any info on this co2 system?

[penguinpimp1990]

hopefully soon i will be getting enough money to plant my first tank. (55 gallons) and i saw this co2 system. does anyone own this and how well does it work? and how often do you replace the carbon block? also could i hook this ph controller up to my co2 system?

Personally, I don't have any experience with them but have read that they aren't very good. Hopefully, someone else will give you feedback.

yeah me too, it seems like an easy way out of c02 injection but its really not that effective ... but nobody here in forums seems to have used one before...
