One more thing... This might sound like a stupid question but, at two sites this system is called the Co2 Reactor 200 With Rio Pump and has the same picture of the product. However, one site says its DIY and the other says its for compressed. (I read at azgardens.com that its for both) I want to buy it from the site that says its for compressed... but I plan on going the DIY route. The product on these two sites is the same right? Thanks for the help.
