Can I use flint in aqarium.

[GroundS.KeepeR]

I want to add some blue flint pieces to my aquarium. What I want to know would this be safe for the fish? Do I need to boil before I add ? Thanks

I found this on the internet:

"The received wisdom I rely on is to generally avoid any rocks with a high calcium or magnesium carbonate content, such as limestone, dolomite, coral etc. as they will disolve over time and increase the pH of the tank and the hardness of the water (especially in tropical tanks).

The best way to test this is either with strong vinegar or diluted acid (such as hydrochloric) which is probably avaliable from a chemist if you ask. If it fizzes or bubbles when the acid is applied it is too calcic for the aquarium."

I think that pretty much answers your question. Happy fish, busy knapping tiny little points of flint. Yak

I have put points in fish tank and other stones never hurt the fish. points look good laying on the bottom in the gravel.

If a artifact is broken so bad you cant tell what it use to be I put it in the bucket. I hunt fields and creeks. Both spots I find broken artifacts but the fields are the worst.

If the rock is clean, i don't think it would hurt the fish. I have seen some rocks be hurt by the aquarium environment, I'm not sure if the water is too acidic or if it's the fish poo, nitrates, phosphates, etc. But some types of rock can be damaged in that type of environment.

I'd guess nice, translucent material like that would be better than chalky materials.
