If anything it would make a sand like material when crushed or ground up.
Is red granite safe for aquariums.
The ideal aquarium to have for using large rocks is a flat bottom acrylic tank but glass aquariums can also be used.
It also would not make dust.
Granite is about the safest rock to put in an aquarium.
These stones are non calcareous and are ph neutral making them ideal best safe rocks for freshwater aquariums whose inhabitants require a balanced water ph level.
But i definitely don t leave it in the aquarium long term.
If it fizzes its unsafe and shouldn t be used.
You may be lucky finding it in nature but they are available in your local fish store.

After finding this out the hard way i now use it to reduce my ph if needed by placing it in the aquarium for a day or three.
If you collect it yourself however make sure you sterilize it by soaking the pieces in hot water then rinsing thoroughly and allowing to cool before use so maybe i will stick with granite remnants only.
They are locally and sustainably sourced.
Granite from my experience is not safe.
A good way to test for safe rocks it to drop a couple of drops of ph down on the rock in question.
Aquarists recommend this rock because it won t cause ph buffering so it is safe for both fresh and saltwater.
There is absolutely no reason not to use granite in a freshwater aquarium.
It is typically an inert stone and will not affect water quality.
It leeches acid and drops your ph to dangerous levels.
