Are these rocks ok for freshwater tank?

  • We are currently upgrading MFK. thanks! -neo
Agreed with pufferpunk, but I dont see a fw rock section, so I guess your kinda a refugee! Ha ha, looks like quartz you should be good. I would give them a good rinse/and maybe soak them for a couple days before putting them into your display tank. Beautiful rock though.
 
They are geodes, break one open and see. I have dozens of these in my tanks, they do not leach limestone because they are not limestone LOL. Breaking them carefully yields two excellent caves when placed upside down or display open side up for appearance. Get more!
 
This is actually a reference to the dog treat commercial, I am not familiar enough with the other bacon references on this board to be referring to that...

Anyway, it looks to me like granite which aside from some minor radio-activity should be aquarium safe, just clean it up real good before placing it in the tank.

It is very cool and unique looking, where did you get them?

Ok I went back and re-read the post, they came from Kentucky, question answered!
