well i turned off the auto feeders, and im just gonna feed once a day

i also have a NP bio pellets comming hopefully somtime this week. Think that will help with the oil slick too?

it isn't really a matter of how often you feed, its how much you feed :-) 4 feedings a day could easily be equal to one person's single daily feeding. However, you could be over feeding if your 4 feedings are quite sizable portions.

As for the oil slick up top, I've found it is quite common with peninsula tanks where you have your main flow (powerheads) at one end of the tank because you're pushing all the water to the other end and by the time flow reaches the other end of that 6' tank it is quite weak so the surface at the other end of the tank doesn't tend to get a lot of movement. As suggested already, you may need additional powerheads to try and point at the surface directly at the other end of the tank or try to move your returns to the opposite end. This is one of the reasons why my returns are at the opposite end of my peninsula. The return a the opposite end to the overflow helps to push the surface water towards the overflow.

my return and my power heads are all on one side of the tank. You think I should run the return on the other side of the tank?

If you can swing it, put a Vortech MP20, or MP40, on the opposite end of the overflow near the top. It will clear it up in no time.

I have created a 'vortech' of flow in my peninsula tank. Returns are split in two. One on each side goes across the top along the edge and two go down along the edge. Then I have a closed loop with two returns each going along the bottom and up towards the Vortech MP20 on the end near the top. I almost NEVER have oil/protein on the surface. Maybe the odd patch right after feeding, and I feed quite a bit. There are no dead spots and everything in the tank is happy.

I know it's money, but it could save you alot of hassles. I'm not sure just you returns will be enough on the end.

Good luck
