''a revolutionary method of producing carbon dioxide for growing aquatic plants.uses electrolysis to free co2 from a carbon block set inside your aquarium.''

anyone ever use this with any success? dr.fosterssmith sells this item.

its bs, when you need to change the rod it cost like $40 might as well get pressure co2 setup.

 

[crazy loaches]

Yeah, its questionable if its as effective as pressurized, and will cost you more in the long run than pressurized anyhow.

I think it eats up your KH (OR GH, I'm pretty sure it's KH)

It's the kH that it eats.

Almost as expensive (or more) to setup as pressurized. More expensive in the long run to operate. Takes up space in the tank. Never really gets decent CO2 levels.

Try the Search function.

I've used it before I knew what I was doing. I wish I had set up pressurized instead. Go pressurized. It's much easier. If you have your heart set on it, I'll sell it for $40 plus shipping. It's just gathering dust in a box anyway. You will need to buy a new carbon block.
