Black Sand Substrate and Toxins?

Thanks, if you have shrimp are they okay with it as well?
I'll probably send the stuff i ordered back, and get that stuff from aqua essentials.


yeah there fine with it the aquatic shop i use use it
in there shrimp tanks as well so i would say no problems
unipack is purely for aquatic use anyway i find it needs a
good washing i find it easy to wash if you use a cotton
pillow case you dont lose so much and it makes washing it
a joy instead of a chore
 
Cheers mate, much help!
 
Dont put it in your tank! Not so long ago I wiped out 3 tanks of shrimp with the same stuff from ebay. Hard lesson indeed, but the dye that they use contains high levels of copper.

Wow, glad i thought of this before putting the sand in the tank, thanks for letting me know!
 
the unipack is ground granite or granite sand
 
Ok, here's the thing. The sand just arrived and it's actually unipac black sand. So it should be fine i hope?
 
sounds like things turned out ok anyway
 
If it's unipack you'll be fine. Mine was non branded but miss sold as inert black quartz gravel.
