Anyone seen or used this??

From what I've read about them, they are only effective on smaller tanks. But the big negative is the replacement cost. Many people trash them, or sell them dirt cheap to avoid the high carbon replacement costs. I recall Tom Barr saying on a forum that Co2 injection is the most cost effective long term means of providing Co2 to aquatic plants. If you think about it, it's true. The most expensive part of an injection system is the regulator. If you shop carefully, it's possible to put together a entire Co2 injection system for about the same or even less than the $200 or so charged for that Carbo thing.

Mine actually only ran $155 for reg combo with pH controller. Of course I already had my own cylinder.

i agree wyld ive got about 130 invested im totally happy with my co2 system refills are about 20 bucks and last about 7 months in my 20 gallon... i make more in plant sales derived from the co2 itself than the replacement cost of the cylinder.... ph control is such a cool thing so why not go pressurized

I used to have one of those carbo plus things. Only thing it did well was cover the substrate around it with black particles. Now I run a blueline regulator on a 5lb bottle. No problems and great results.
