    Polished River rocks aquarium Safe?

    Was at the dollar store with my girlfriend and saw some black polished river rocks. This would make a very nice addition to my aquarium but they do not say anything about aquarium use on the bag. Ive done alittle research about picking out aquarium safe rocks and majority of the posts say to use vineger to drop on the rock and see if it will foam or fizz. I just dont want to assume since it says polished river rocks that there hasnt been anything added in them.

    I have kept polished river rocks in my setup at one time and they worked out fine for decoration. If you are using it for substrate, however, they should be more like tiny polished river pebbles.

    I have some that I bought at Home Depot that have been in my tank for a year with no problems, and I know my mom has had some in her tank for several years. Mine didn't say anything about being aquarium-safe, either.

    I don't use them as substrate, though, just a few pretty ones scattered on top of regular medium-size aquarium gravel.

    Its more than likely they are safe. I remeber seeing them for sale at the lfs. If your still worried, soak them for a few days and rise them off good.

    I've used the polished rocks from the dollar store for a while without any problems.
