I started a 2.5 gallon nano tank a few months ago. I have a blue damsel in it for now and want to get some coral after the tank gets a little more stable. My problem is that I get a film on the top of the water sometimes. I had the same problem with my 20 gallon tank until I got some more water movement on the surface. I have a deep blue nano HOB filter on the 2.5 gallon tank and it just doesn't move enough water around on the surface to get rid of this film. Is there a better filter I can use to get more movement for my little tank?
