Try playing with your tuning I place a mark where I have it set and if I remember correctly more air is wetter skim less is dry skim it could be gbe versa I can't rember offhand but it takes a bit for the tuning to take effect it doesn't take much turning for my skimmer to see a big diff. I've never had your skimmer I can only assume there's a air intake you can adjust???

This is 100% correct, I have seen way too many tanks with oils slick syndrome, always have the surface water move to the overflow box.

The foam in the overflow box doesn't sound quite right either, is it falling for quite a drop after going over the overflow? sounds like the overflow is acting as a skimmer.

there is no initial drop in the overflow box

Im coming up with a design to put the returns on the opposite side of the tank as we speak (or type). Its probably going to be on top of my light fixture so it wont be seen.

how much of this have you changed?? how many fish are in your tank in total i browsed through your thread and i cant get a solid answer but i seen alot of tangs and clowns lol:):)

sorry was for your nitrate thread but i have a feeling both are linked:):)

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
