Hi guys,
I have been running my BiUbe for a while now - everything seems to be going well. It has 2 Zebra danios, 3 mountain clowns and a couple of golden zebra danios. The water recently tested had both ammonia and nitrite at zero - with nitrate at 40. I am now seeing brown slimy stuff starting to grow on various items in the tank - some stones and plastic leaves. It is almost a rusty colour, but comes off easily. I cleaned it out the other day during a water change, but I can see it coming back again. Fish seem OK at the moment.
What is causing it ?
Cheers.
