Aquarium Rocks

[GoldenMonster]

Hi there people. I was wondering if someone would be able to inform me if you can put Lime Stone Rock in your aquarium. I have some fossilized rock dated from dinosaur ages, im not sure exaclty what age but defineatly prehistoric. Thou its rock it emitts a small dose of "I am old rock" smell. Is there anyone who could tell me if there would be risk of contamination to the aquarium/fish? Im only sure that I got it in canada and am not sure of its exact origin or if its been exposed to any other contaminants. Looks clean thats about it, I left in water for near a month before and didn't show any sign of loosing integrity when submerged.

Limestone should never be placed in an aquarium as it will drastically alter the water chemistry. It will greatly increase the water hardness which is not good unless you are keeping african cichlids.

As you have posted this in New World Chiclids, I take it you have chiclids only in your tank. If that is the case then limestone will be ok for you as chiclids need a higher ph than other freshwater tropical fish.
There is a pinned topic on rocks in the Tropical Chit Chat forum.

Not correct!! Mbuna need a higher Ph, but most NW cichlids need a more neutral Ph, so I still wouldn't add limestone if that is the type of fish you are keeping!!

All cichlids can and do adjust well to a higher ph...as long as it is not a ph that is continually changing ,they would be fine.

Thank you
I sit corrected
Then plese disreguard my previouse advice GoldenMonster
Rvm is more experianced with chiclids than I.

As blueice said, most NW cichlids will happily adapt to a higher Ph (mine live in water with a PH of between 7.5-8), but why raise the Ph when you don't need to. I understand that you want to add this rock, but unless you have water with a low Ph, I wouldn't add it!

They may be able to adapt to a higher pH, but many still prefer a low pH. Discus, angels, rams, to name a few...

To say that all Cichlid can adapt to high Ph nonsense.

There are many cichlids that prefer a pH great than 7 this is true with one Cichlid living in the most alkaline live fish in the world with a Ph of 11.

But there are many west African and south Americans that would not survive long at a pH of 8.

There are some Apistogrammas that would not be happy with a Ph over 6.

Drip a small amount of vinager onto the rock, if you see bubbles dont add it to your tank. Most marine fossils are found in lime stone and are not good for community tanks.
