What do you call that stuff on the top of the water :)

From the top looking down, the water is clear and beautiful to look down at. But looking from the bottom to up top, you can see this film that covers the top except for the spot that the powerhead is blowing. How is this removed? I remember my first tank (55 gallon) had this same film and it was not reef ready as well. I had two powerheads and always had this stuff on top, but I'm guessing it was my lousy Red Sea Prizm skimmer. My last tank, my 100 gallon reef ready, never had this problem, I'm guessing cause of the overflow. Anyway, is the film a problem? I'm getting my new skimmer next week. Hopefully that will help, but just wanted to see what solutions I could come up with

It's unsightly and it reduces the oxygen exchange...so it's not good.

Usually some sort of surface skimmer (overflow) and breaking the water with flow or redirecting your flow will keep this to a minimum.

Agreed--this is your problem.

Need this or something similiar.

Try mounting a powerhead at the end opposite the internal overlflow box.
Aim it so the it ripples the surface and pushes water towards the overflow.

Not to sure how good these work. But it is designed to do what you are looking for.

I think I got the problem solved, or at least did have it solved, but then battled another problem.

I thought having a Maxi Jet 1200 with my Koralia 2 would be great flow for my tank. But I was wrong, sand storm like no other, no matter where I put it. So I unplugged the jet and am looking for a Koralia nano or Koralia 1. But I got definately got rid of the film with the two jets working
