Skimmate problems!! Help!!

[Rogue951]

my bad never used RSM. assume d it ment 130 gallon.

most I used it on was a 20 display and 10 sump.

and if I remember right there is no back chamber?
2 vertical chambers stacked up.
no actual pump to move water in/out, relies on diffusion.

Actually it has a back chamber and 2 return pumps.

Check the display portion and make sure the water level is below the upper rim. It's one if the design problems of these setups. It won't skim the surface if the water level is to high.

Also point one of the pump outlets towards the surface.

I've had an rsm for 4 years and have experienced this multiple times.
