240/3 skimmer stopped skimmimg ??

Hi Roger,

I'm not sure why but my Tunze 240/3has produced almost no skimmate for about a month now.

A friend has suggested that because I'm running Ozone thru a supplementary skimmer that it may be affecting the surface tension of the water and hence the skimmers performance.

I've had the skimmer and Red Sea Ozoniser for about the same length of time and the skimmer has never really been very prolific as far as producing skimmate is concerned. Is this a possibility because there is sufficient bioload generating waste within the system and the skimmer appears to have been set up properly ?

Ozone oxidizes the conatminants the skimmer would remove so the skimmer is less effective, you basically destroy the protein molecules so their is nothing left for the skimmer to pick up. I have always found ozone impairs skimmer function unless it is an extremely low dose like less than 10mg/hr per 400L, which is just enough to clarify the water but without much of any sterilllant effect.
