I was traveling most of the week, but did have time to do a few cool things quickly this afternoon. I just brought my test co2 online. This is pretty cool. Part of the biggest issue is that paintball canisters do NOT fit our regulators. I stopped into
Paintball Ohio on 71 last week looking for help. In discussion, it actually came out that Aquarium Adventure is in there every few days. Wait... AA is ahead of the curve on stuff I can't find anywhere online? Of all places, yes AA has the adapter for paintball canisters to our regulator (blue part in picture). Paintball Ohio has a pretty cool program too. $26 buys you a tank and a full year of refills. That could be once a day or once a year. The cheapest I could find this canister was $20-22 online, so that's only $4-6 for a year's refills. Pretty good deal I think. It's hooked up to my 618 right now. I think I might get an extension hose so I can mount the canister separate from the regulator under the tank. You can see the drastic difference in size.
They do NOT put oil in (issue #1 for this use) and should be using food grade co2 (they do beer keg co2, pop machines, etc).
