….I'd like to tie some java fern to and add it to my 75g. Question is, the rock has been sitting in a tank I recently dis-assembled, in water just enough to cover the gravel, is the rock ok to put in an established tank as is or do I need to clean it up a bit?.

I would just rinse it under the hot water tap to remove dust and dirt. Or you can do this in a pail of water. Clean off any algae, a brush like an old manual toothbrush works for this.

Thank you Byron, your advice is always logical.
Appreciate it.
