Fresh bone is roughly one third proteins, one third a mineral called hydroxy-apatite, and one third water. Duh! To test a rock for this, put drops of ordinary white vinegar on top of the rock. It is harmless to even sensitive creatures like shrimp. Yep, someone came up with this ludicrous claim on Facebook. all water except distilled and RO) and all adult fish do fine. The only radioactive mineral one might possible very rarely come across is a very rare yellow crumbly mineral called “carnotite”. Mica platelets are soft.

First off oil shales are very rarely found near the surface (in the United States this is limited to Southwest Wyoming). Yet everyone and their uncle will keep telling us to be careful about all that poisonous rock out there in nature. And then there are the folks that come on social media with comments like “I added two rocks to my aquarium and the next day all the fish were dead“.

If it fizzes then no it's not safe. If the rock looks inert (gray shale-like rock, no sand comes off when rubbing it) I usually don't even test em, just scrub em with hot water and in they go. Turquoise is an extremely insoluble hydroxy phosphate mineral. Any form of calcium carbonate (“bubbles in vinegar”, limestone, coral rock, shells) can slowly raise the pH of the aquarium to 7.6 to 7.9 pH, no higher. A good way to test for safe rocks it to drop a couple of drops of pH Down on the rock in question. Another way to test it to take some water and put it in a bucket. These minerals are NOT permeable.

Sometimes manufacturers coat the rock with mineral oil to make them more attractive. It simply means it will harden the water and may raise the pH. Proper vinegar dosing will decrease nitrate levels by increasing bacterial populations, which are then skimmed out removing the nitrate within their cells. You do the math. Be prepared to remove the rock and do water changes/run carbon if you see problems. Note that “store bought rocks” can have a small problem. There is a HUGE difference between heating a rock in a fire pit and heating a rock in a pot of water. So even if you are in the oil shale regions of Wyoming the oil shale rocks you might possibly find are totally harmless. In any case even if these highly insoluble materials were somehow able to dissolve in water, the resulting solution would be completely and totally harmless. answer #2. big_sw2000. And every single list will be 100% wrong! This just goes to show how much incredibly false information is out there in the web. If drops of vinegar are put on a rock which is calcium carbonate, the vinegar is too weak of an acid to “fizz” and bubble. If they dissolved in water why are they still in a rock which has been soaked by groundwater and rain for several million years? Isn’t it interesting that streams tumble over all sorts of rocks, including one’s that fizz, geodes and crystals, yet the fish aren’t somehow poisoned or affected in any way?

If calcium carbonate dissolved more than the tiny amount that gives a pH of 7.6 to 7.9, these mountain ranges would have dissolved away millions of years ago. River rocks are not often sold at aquarium shops, but landscape suppliers have plenty of them. The person takes out a very hot stone from the fire and places it into the water (probably a 600 to 800 degree temperature differential). It simply cannot happen without violating several basic laws of physics. i didnt plan on leaving the rocks in tubs until today but with no circulation i'm sure the rock is going to be bad.

The most common form of “sparkles” in a rock is the mineral mica, an insoluble silicate which is very safe in the aquarium, contrary to the many social media “experts” claiming it is poisonous. Shells and corals are also perfectly safe with no treatment as are ALL gemstones, semi-precious stones, tumbled rocks, geodes and crystals. All these minerals can be ground into a fine powder and eaten by a human with no effect. (note oxygen will be trapped in the holes of the rock and will escape, but that looks different). Naturally, a stronger acid (pH Down, pool acid, etc.) Hello, can anyone identify this type of rock and know if its safe for aquarium fish?

Still other sites say that amethyst, agate and rose quartz are bad while quartz is fine. Almost all geodes are quartz. I did this and it is working out fine. Note that the author is a degreed professional chemist and research scientist with a mineral collection with well over 1,000 specimens. But keeping water under pressure such as it is inside a rock raises the temperature required for the water to turn to steam (a basic law of thermodynamics!).

The dyes used are completely harmless to fish (typically aniline or phthalocyanine dyes). (Quartz is one of the higher rated stones.) And the chlorine killed the fish. Since most rocks are not pure minerals it may fizz in one spot and not in another, or the calcite is diluted in the rock and it will barely fizz. If extremely fine dust of virtually any mineral is inhaled into the lungs of a human there can be health issues such as silicosis.

I have always been told lava rock was inert. It's always going to be a gamble using anything you find outside. If the vinegar foams, the rock is calcareous and this will affect the hardness and pH of the water.
