polished rocks

[pucknut]

was going to silicone some polished rocks ( purchased in Michaels craft store) to pvc for caves.........but, i see on bag, it says not for aquariums......i thought for sure that i read that they were ok

They use a polishing powder that would leach into your system most likely. I would avoid polished rocks.

Oh No!! I have had polished rocks in my 90 Gallon Freshwater tank for 4 months now. I had them soak in a bleach solution for a few days and then I soaked them in a bucket for a week in freshwater. I couldn't image that polishing powder would still be on the rocks!

Any idea what these polishing powders could do in a tank?

Should I take them out now...or has the damage been done.

I have had little problems with the tank (except for Algae Bloom). I have had no deaths...and somehow 3 baby Cherry BarB Fry have survived in this communiy tank setting.

I do not remember seeing that they said "not for aquarium use". I got mine at AW Moore. Hopefully it is a different brand that CAN be used in aquariums.
