Can I keep an amethyst rock or quartz in aquariums

[jacobfata]

My fiancé has a collection of beautiful rocks that are amethyst and quartz. Do people use these in aquariums? This would look beautiful with my white sand in my discs aquarium but I imagine it would also cause some major water and ph fluctuations! So... are these rocks safe or dangerous? I think I know the answer already.

Can I place these glass crystals in my discus aquarium?

Yes both quartz and amethyst are inert so considered aquarium safe, they won't alter your water parameters. My only little personal concern would be whether the amethyst was so sharp it could scratch or damage a fish, but I'm admittedly a worry wart about such things.

So you’re telling me this is safe to put in my aquarium with ten discus?

It seems risky, like why wouldn’t everyone do it? Lol

All the time. Do you have sand? ......

Yeah, well hydrochloric/muriatic acid is easier to use as it makes more bubbles, but vinegar still will work, just not as obvious

You can pick up muratic acid at home depot it will like said previously react more noticeably. The Crystal is inert but if there is rock attached you need to check it.
