Wait....so your setting up a 30L and 10G when you go to college? Are you going to be living in the dorm? haha...I say you go pressurized if you can, when you are in college you wont be having alot of time making diy mixtures.
Hey, sorry I didn't see your message earlier. Um, I'm pretty set on getting a 30L to set up once I get settled in. I might also have a 10 gallon for shrimp. Who knows. I really want to get pressurized!
