Alright so first off I have a slight film on the top of my water and I notice several other tanks at my reef store also have it is it normal? Or just from a newish started tank? Also how do you get pods
in your tank?
Edit thought of one more question for a 55g are protein skimmer and sump neccesary to start with or can. Wait until. Go back to work (landscaper get a nice winter break this year had almost o snow in syracuse)
