SUPERIOR TO LAVA ROCK: Over time, porous lava rock becomes clogged with debris decreasing its surface area so that its ability to house and grow good beneficial bacteria plummets. Our bio balls’ uniquely spaced spines allow most debris to pass right through them. Lava rock has tiny pores which make it difficult to clean while bio balls in most applications never need cleaning. A bag of wet lava rock is many times heavier than our pond balls.
SPONGE FREE BIO MEDIA: A huge problem with other bio ball filter media is that they have a sponge in their centers to increase surface area, but sponge pores trap gunk that does not wash away. This trapped gunk reduces water quality. This problem is solved with our bio balls! How? They have a small solid center covered in spines that won’t trap gunk. You never have to suffer with poor water quality. Made in USA
