A strange thing

[Fiddlesticks]

I have a 20 gal that I just moved the inhabitants out of 4 days ago. Im going to have to establish the tank again so I can use it for quarentine. Anyway there is still water in it, and I noticed some fuzzy brownish green sort of moss or fungus growing on the gravel. Is that normal? I was just wondering if that is the little beniful bacteria dying. Just curious, because now I have to clean out the tank and re-establish it anyway.

It sounds more like diatoms (brown algae) to me and should go away in a month.

Cool thanks Iv never seen that before.

You can get proprietary chemicals to remove it or you could increase the amount of fluorescent light or sunlight (I'd choose the former ).

Ah thats a great idea. You might be onto something there, because it only appeared after the light was off for 2 days.
