Can Gemfoam be purchased separately?

Yes, we do sell the Polishing Foam separately.

What is the difference between this and product # ngbulkgrit?

Thank you so much for your inquiry. This item (the Complete Media Kit) contains the grit along with GemFoam to assist in the polishing stage and Ceramic Pellets to reduce rock breakage along with making the tumbling process more quiet. The Bulk Grit does not contain the GemFoam or pellets, but does contain the grit.

How much of each medium is included in this accessories set?

The jars shown hold approximately 2/3 of a cup, so plan on buying bulk bags in the near future.

My lid cracked and i need a new one. Are there replacement parts avaliable to buy?

Not sure if you are referring to the tumbler canister lid but you will find replacement parts on Ebay under rock tumbler parts
