surface skimming

[mike]

What can I do on my habitat 30, always get a slight scum floating on top?

[Reefraider]

When you do a water change get a jug push it into the water and just break the water line so the water surface flows into the jug, I do this with every water change

More surface agitation so the scum circulates in the water and reaches the skimmer

[terrac]

aim the return nozzle to the surface more to keep the floating scum in suspension so the skimmer can take it out. or drop your water level so it goes into the weir at the back

I get it if i've overfilled the tank slightly in relation to the return nozzles position. otherwise surface keeps clear.

Lay a sheet of kitchen towel on the surface and it should remove it, its a good idea to get rid of it because it can reduce light penetration.

I also have the nozzle pointing at the surface and the water line half way up the weir , results in a clean surface
