Great design These were a great design very sturdy and ideal for any filter system for a tank or pond. Highly recommended
My fish are happy 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.
