New CO2 Products

[GIS Guy]

I was looking through the Dr. F/S catalog for Fall 2006.
On page 131 they have added 2 new products for CO2.
The prices and sizes draw my attention.
These products may be a better way to go on my 20g.
.
One product is a regulator system for paintball cylinders.
Freshwater Planted Aquariums & Plant Care: Carbon Dioxide CO2 Pro Systems
.
The other is a regulator system for disposable CO2 cartridges.
Freshwater Planted Aquariums & Plant Care: Carbon Dioxide CO2 Green NRG System
.
Perhaps I could solicit MFTers for opinions such as:
...effectiveness;
...size of tank;
...duration;
...quality of equipment;
...you know the rest, etc.

Well, they won't last very long. The second one says 260 days at 4 bubbles per minute. That's one bubble every 15 seconds. That's not a whole lot of CO2. I have my pressurized system between 1-2 bubbles per second.

Now if those were going to a passive CO2 diffuser, like an upside down cup or whatever it's called, where it fills up with just CO2 and you run a powerhead across the bottom so it disolves the CO2 from the cup into the water, it could work for the 20G. But most of those systems I wouldn't recommend unless it's under 20G.
