I purchased this to hold crushed coral in so I could add some to my canister filter. It worked as expected and holds all the crushed coral I need! No leaks, no tears, no snags, just a good bag for all your substrate needs.
Great awesome purchase
These were great for improving my hang on back filter.. loaded up with bio rings it is a perfect thong to make cleaning easier.
nice bag for the bio rings...came in real handy...kinda pricey for just one but i think it will last awhile...great service and great products..thanks again Cory
It holds my bio rings and shows no signs of wear after several months
