Tank and hopper

[patamoose]

Im going to get an Electra 08 this week, and I was wondering what tank and hopper I should get. My current tank for my Tippmann is a 9 ounce Co2 tank. And I dont know if that will work to well for the Electra. I dont know what tank to get because on actionvillage.com it says that anti-siphon is recommended. And I have no clue what that means, or what is a good tank that wont make the gun front or back heavy.

Now onto the hopper. I currently have a gravity fed 200 round Viewloader. But I dont think that will cut it for the Electra. So what hopper do you guys have for it?
