Brown layer on top of my water

[Trevor Robertson]

Thought that I would update everyone as to how this is going.

Well I finaly got out and purchased a second 802 powerhead with a filter on it and when I got down stairs to put it into the tank I noticed that the brown layer was...gone!

Well I guess the sit back and do nothing worked just fine in this situation. Well I put the 802 in any way as I think that I will need a 2nd powerhead in a tank this size.

Thanks for all your help, I am sure I will need it again I think that I am getting a clown or two this weekend.

PS does it affect you bio load when adding clean up crew's like snails and hermit crabs?
