Pink frosted rock from Big Al's

[Kait]

I know this is a major long shot, but does anyone know what kind of rock the pink frosted/sheer rock from Big Al's is? It dissolved a bunch in my tank and I'd like to identify it so I know what I need to do to make sure everything turns out ok.

Thanks in advance!

sugar.a pic would help.sounds like it has quartz in it.could be rock salt if it dissolved(hallite)

I'm gonna guess it's Himalayan rock Salt. I'd take it out right away and do a major water change if it's dissolving.

This is the rock in my tank - it looks like an ice cube when it's wet. I'll get a picture tomorrow when it's dry.

I was thinking it looked similar to quartz too, but really know nothing about rocks.

If it's rock salt, will it change the salinity? My salinity levels are good.

Will work on the water change tomorrow.

not good if dissolving and little surprised they would sell something that did. I'd be taking it back for a refund and get them to add in some salt for your water changes.

Could be calcite.

gypsum,limestone-both can dissolve in salt water

Why would you put a clear rock in there anyway ?? Just askin .... In a couple months it would be covered with algea or coraline anyway did big als tell you to get that or something ?

[Kait]

It was pretty. I knew it would likely get covered in coraline, but it was a unique shape and I figured I'd enjoy it while I could. Plus we were speculating whether coraline algae would stick to it anyway… or if snails would chip it of like they do the coraline on the glass.

No one advised me to get it or not to get it. I wanted something more decorative for my tank that wasn't a terrible ceramic/plastic thing.
