Como 50 Black Aquarium Fish Tank Filter Bio-Balls Filtration

These were a great design very sturdy and ideal for any filter system for a tank or pond. Highly recommended

I was going to throw away my top-fin 50 gallon filter before I saw Bio-balls used in a Make: magazine article. I tried the Bio-balls in place of the recommended filter and it works great.

These are a bit smaller than I expected them to be, but they are still a great deal. I'd say they are about 3/4" in diameter. They came in a black mesh bag which I am using to contain them in my filter. I just put them in today. I'll update my review again after they have been in there for about a month to let you know what I think of them them. But so far, so good. And the price was a great deal! Can't complain about that at all!

I am big on biological filtration and these are new to me, unlike anything I've used previously. It takes time for this kind of product to show its best features, so I'll be back later to fill you in on how well this product works.

These bio balls have some weight to them. I did not use the net zippered bag as I divided the balls up in my filtration system.
