Spacer Pellets

Protect your rocks as they tumble and you will end up with more great rocks and less breakage.

Be sure to use some sort of spacer or filler for your barrel. This is especially true if your barrel is not fairly full. Spacers, like the plastic spacers we sell will protect your rocks. Also, in the final phases of pre-polish and polish spacers will also protect your rocks. Our plastic spacers are reuseable. Take a look at our spacer collection.

Grit Disposal

Do not dump the used grit and polish down your drain as this is very likely to clog you pipes.

Try to group rocks of the same hardness together in the barrel. The Mohs scale is a great resource to find out about hardness of each type of rock.
