Bio bubble nano reefs

[Loomin8]

I am a new member and struggling with a small pico tank. I received a bio bubble for Christmas this last year and haven't been able to find anyone who has or had one that is willing to share experience. It's been established about 3 1/2 months and developed a rotten egg odor that is coming from the sand . I do partial water changes every two weeks and It's been cleaned recently. I have live rock, live sand and filter is working. Any ideas or advice would be appreciated. It stinks!

From my experience some sands will stink especially if you have a deep sand bed. I have found keeping it stirred up will help the smell get better.

I'll stir up more often. I also recently cycled so maybe that contributed.
