These bio rings are made of sintered glass. Great for improving your biological bacterial count in your aquariums. Common used in Canister Filters, Hang on Back filters and sumps. The bio rings weight 1lb 2 oz or 500 grams.
The order process with Aquarium Co-op was seamless. They are clear and concise in their response emails. My order came in as planned and I will be ordering more from Cory and his team.
Thanks
