How to create a vortex?

Hi,

I have a 2080, and a 2217 running on my tank with a spraybar at each end and inlets at each end.

I have a film on the top of my water, i think it is residual protein as i have nothing breaking the surface of the water.

I cannot stand the sound of running water so I cant move the spraybars about the waterline to break the surface, also i cannot fit a HOB, my tank does not allow for it!

Is there any way i can either make a diy surface skimmer that i can attach to the inlet of the 2217, or is there some way to create a vortex that will suck the film down into the tank to allow the filters to collect it?

thanks

You could switch to a drilled tank with overflows.

thats not really an option...i just got the tank! is there any way i can drill the tank with my fish in it?

also overflows will not pic up all the crap from my plecos will it?

thanks

Just add a Tom surface skimmer to your canister intake. Really simple addition and clears surface residue for good.

would this still allow in the inles from the canister to pick up the poop on the bottom of the tank?

thanks

Did you try rotating the spraybar so it slightly ripples the water surface AND doesn't make any noise? This method can be done with the spraybar located under the water surface.

yeah i have my bars on both end rippling the water surface but no good.

I need something to break the waterline, i.e. create a vortex or a surface skimmer that allows inlet from the top as well as the bottom!

Any ideas?
