Cycling done, now another issue!

[itsstace]

Hi, I've just recently finished my fishless cycling. Turn on my lights today and saw lots of White fluff on the wall and some ornaments. Can anyone advise what this may be? And what should be done? Thanks

This is a common occurrence after the initial cycling period has been completed. It will usually go away on its own.
