Surface Scum

[mr86mister]

I'm trying to figure out a way to remove my surface scum in my system. I do not have an overflow or sump system. A simple 20L with an Aeroforce Skimmer/Refugium. I currently have the outflow and a Koralia Nano keeping the surface stirred up but I still can't figure out how to get rid of the scum. Any ideas?

Aside from trying to get the stuff back in the water column as you're doing a surface skimmer box is the only way I know of.

surface agitation will help but may not eliminate it 100% ,maybe you can point a power head upwards to mix the scum into the water column. also

how much flow does the skimmer/fuge draw? Could you build a small overflow box around the intake?

Eheim used to offer a device called the surface extractor.
I don't know if they still sell the thing but if you find a picture of one I'm sure you could copy the design and DIY.

Jackson-It pulls in about 200gph. I guess with the combination of what you recommended Gary, there is a possibility I could somehow rig up something in the system. Hmmmm.....

I used to mount my standard powerheads upside down with the motor part on the bottom to get good surface agitation.

make a custom surface skimmer to connect to your protein skimmer itself

The new Aeroforce skimmer has two pumps. One that draw the water into the chamber and another one that just draws in air to chop up and put up the chamber. I'm looking into possibly hooking up something to my nano pump into the fuge.
