I am currently setting up a fish room and so far I have a Alita Linear AL-60. I really don't know much about bigger air systems and was wondering what else I will need with it to set it up. I am going to set up 6-8 40 gallon breeders maybe 2 30g and 3 20 long. Is there anyone who knows a lot about setting up a fish room who could help me out with questions? Right now I really only have 180g, 150g, 125g, 2 75g, so mainly these would be for breeding. I am also wondering where would be a good place to order some sponge filter online for cheaper prices. Any help you guys can give would be really appreciated.
