Idaho lava rock in an aquarium?

Is black lava rock from Idaho safe for use in an aquarium esp with freshwater shrimp?

I am from Pocatello and I have used local lava rock in both my 29 gal and 10 gal tanks. About 8 week ago I got some RCS for my 10 gal and they are just fine, In fact 2 are carrying eggs now and one has gave birth to about 35 babies. I have also had a group of 6 Amano Shrimp for over a year, it was 9 but I know my cat is responsible for 2 deaths. All my fish do fine. Some of my plants do great, some dont, but I think thats my fault not the lava rock. So I think that our Idaho lava rock is fine.

Our Utah lava rock works well for me.

I'm not new to fish or plants, but am new to planted tanks. It is fun to learn new things and is a great place to do it.

Hello Apol...

I test the rocks I put into my tanks with organic apple cider vinegar. You can get it at most chain grocery stores. Just put a few drops on the piece and if there's no reaction, then you can rinse it well and it's tank ready.

If there's a reaction, then it shouldn't go into the tank.
