JIH Aquarium Bio Ceramic Rings Filter Media for Pond Fish Tank Canister Filter (4 lbs)

I ordered these to use in the sump of my saltwater tank, and I’ve had to set up a hospital tank once, and was able to grab a few of these out of the bag to get the biological bacteria to start in the hospital tank!! So glad I got these!!

Can’t go wrong. Just rinse them first.

Not the best but it works, only thing is you really have to clean it to get all the dust or whatever off of it. Still would recommend it’s a good price for media bags.

These ceramic rings are great for my fish tank filters. However, they were much smaller than I anticipated. Came in 2 separate zipper baggies which was great! I used both bags for 2 filters

Great product Great price.

Muy bueno

used as bio material for my pond. Its good size to create good bacteria.

I took Dimensions because some people might want them and then I had time to kill and I decided to count how much in one bag was I would say the average of one bag 232 pieces. I just got them we’ll see how they do

Definitely worth the price for $20

half of the stones in the bags were crushed and thrown out. Looking for a better product.

Por 1.8 kg esta muy bien el precio

Works great as a biological filter.

Nice quality ceramic rings, somewhat larger in size.I was able to place them into my Fluval 4 immersed filter but these will not fit into smaller or flatter filters. My Fluval bio filter case is box shaped with about 3/4” thickness, so it was fine but my original ceramic rings were half size comparing to these ones.Mind this when buying it for smaller aquariums.
