Now, I know very little about aquarium CO2 systems, but from brewing beer, I can tell you that the difference between those two systems is that standard version will take a regular CO2 tank, like for a soda dispensing machine, and the Paintball version will take a paintball gun CO2 cartridge. I believe either of them can be refilled. The difference being that you can take a paintball charge home in your pocket, whereas a standard CO2 tank (even the smaller ones) has some heft to it (Think like a full sized fire extinguisher for a small CO2 tank). The paintball charges would have to be refilled much more often than the standard tanks. How often that amounts to, exactly, I don't know. So it's a balance of convenience vs cost. Paintball cartridges will probably cost more in the long run, but they're a lot easier to move around and store, and the cartridge itself is probably less expensive than a standard tank (but not so much less as you might think). The standard tank is harder to move around, probably costs more in initial outlay, but only a bit more to refill, and lasts much much longer, so you won't have to move it often.
