Remind me if you are using fish food to cycle with as it could be down to this if yes
yes I was - I have removed the food now as the amonia levels shot up, the tank stinks and this layer of scum formed.... just scooped as much as I could out and added some mature media to my filter plus added a small amount of water from a mature tank.
Is the scum red? If so i would say its coming off some with is painted or dyed red/brown. I personal do at least a 30% water change syphoning water from just under surface aimed at the surface so the scum is removed totoaly, does that make sense
No the scum was white. As the 'fur' dropped to the bottom it turned dirty grey. I believe it was a bacteria or algae bloom caused by the fairly still water surface and the high water toxins from the food. I have since Altered the filter output to use the spray bar pointed towards the surface and its cleared up. I've also added the food back in but in a smaller quantity. See blog for details. Thanks.
