If anyone knows whether or not it is ok to use feather rock in a fish tankor not, please let me know. And ifd if it is ok to use, then how will it effect the water chemistry? Please help!

I've seen it used many times, it's always been fine. I think you have to boil it to get it to sink.

I don't think it has any effect on water chemistry.

I've been using feather rock for a few years. Do a search for it & you will find lots of comments. I boiled mine to get it to sink.
