NUOMI Black Aquarium Fish Tank Filter Bio-balls Filtration Media 16mm (pack of 50)

Short Review: I mix these with the larger balls and ceramic bio media that came with my filter.. these balls are great, they are small meaning they are awesome for filler media! They are high quality! And they have a foam center for more bacteria!

Pros
1.) Small – I know to some, these balls being small is a downside! But that’s why I purchased them! They make great filler media to go with the other media already in my filter!

2.) Foam Center – Great for bacteria growth!

3.) Value – Excellent value. The are 75% cheaper than local pet stores and 50% cheaper than Big Box Stores!

4.) Bacteria Growth seems to be great on these!

5.) Bacteria grows quickly on these

Overall: I highly recommend these to anyone needing media! If you need a lot of media I’d suggest ordering extras! These are small but Excellent!
