well thanks guys for all the help and advice! im still doing some in depth research, and I looked at a couple pics and saw that this is the whole setup (is it?). if so I guess its harder explained than what it looks like lol I see the regulator and bubble counter, check valve, etc its marked. is that all I should need there? GLA is prob. going to be my main go to brand.
Bump: now the one thing in this pic that idk about is the solenoid, what is that for? also the tubing leads off, so I presume it goes to the actual aquarium
