My understanding is that's a bit "different" than something like greenstone or other aquascaping stones. Those can release KH into your water which can cause weird fluctuations - at least, that was what I was told several years ago, and lead to me removing the rocks from my aquarium.faydout said:Wouldn't most substrates just be varying sizes of tiny stones?
All rock are not the same. Some like limestone can affect the perimeters. For examlpe, It can be used if someone needs to raise the PH in their tank. Others are totally inert and have no ill affects at all.zorianak said:My understanding is that's a bit "different" than something like greenstone or other aquascaping stones.

ok thanksA201 said:I think the Green Stone you are referring to is a porous igneous rock. My guess is that its inert, like most lava rocks commonly found in aquariums.
Considering its being offered by an aquarium decor company, probably fine for your tank.
I did contact them. Thanks!julkosi17 said:You can contact manzanita driftwood and ask them about that. They have great customer service.
Hmmm...A201 said:Never seen that variety of rock before.
Thanks! This is a very useful tip to use that I didn't know. Interesting. That's confusing that there are so many different things that could make up green stone.wisecrackerz said:Looks like there are a lot of things that can sold under the name "greenstone." Because they're all different minerals, they'll all have different chemical properties. Some may raise your pH, your K+, or Ca+.
The best, quickest, and easiest way to test the "greenstone" in question:
Put a sample of the stone you're wondering about into a clear Tupperware container, full of white vinegar. If tiny bubbles form on any part of the rock, you have evidence of a chemical reaction between the acidic vinegar, and basic rock. This indicates that the rock would cause a change in your tank parameters, and is a poor choice as a tank ornament.
"Greenstone artifacts may be made of greenschist, chlorastrolite, serpentine, omphacite, chrysoprase, olivine, nephrite, chloromelanite among other green-hued minerals. The term also includes jade and jadeite, although these are perhaps more frequently identified by these latter terms."
Hmm ok. I wonder why they do this...wisecrackerz said:It's because "green stone" isn't really the name of a mineral, as opposed to things like "jade," or "emerald." It's just what that particular retailer is calling a stone they sell, because it happens to be green. It would be like buying "white stone," or "smooth stone;" it's just an adjective used by the retailer, rather than any kind of scientific terminology.
I agree, but I specifically wanted smooth rock for the look I am going for.A201 said:IMO, better to use porous rocks, ones with holes & crevaces, or rocks that are easily stacked & leaned. All aquarium rocks will turn green soon enough once algae takes hold.
