Perfect size and media bag has a zipper
I like this item for its size and options to change the amount to media in the bag. I used this for my saltwater tank to help with bacteria growth. Perfect buy!

Bags and balls flout..
Got these for a sump. Been in 3 or 4 days now have yet to sink. Nice plastic balls will a little form inside in a pouch but the flout so not super helpful. Good for a canister filter I'm betting.

Good value. Exactly what I needed.
I had 2 filters that had a little extra room for bio media so bought the two pack and they worked exactly as needed. Every water change I swish the bag of bio media around in old tank water and replace. I wouldn't hesitate to buy these again. The reason I preferred to add bio-balls to my filters is I already had (established) Seachem Matrix in them (more than enough for the bio load of my tanks). Adding a denser material will decrease water flow and will clog faster. The bio balls work well and because of their design, allow water to flow through them easily. So now my filter basket is full of bio media but not jammed so tightly that water can't flow through it.For new aquarium owners, bio media becomes less and less important the longer your tank is established and mechanical filtration is always most important (with regular water changes).

Keeping the tank clean better than the filter
I don't know if the filter we had sucked or what but these certainly do a much better job than the filter!

Great Balls!!
Super great value for canister filters and HOB even. I even pop some in tanks to use in new tanks to help setup bacteria quicker. I like the sponge interiors, more surface area and also better at catching smaller particulates. Would only buy these at this point and pricing point.

Cheap and best
Great product and value for money. This is the cheapest product as well as best in quality you can find in Amazon but you will not get the net bag with this product

Good quality Bio Balls but no net bag as shown in pictures.
Bio Balls are of good quality and has sponge inside. Black zip net bag was not provided, instead a low quality nylon net was sent. Anyways it does the job. Bio balls are going to last lifetime so this investment is worth it.
