Bio Ball 1-inch Small Bio Ball for Aquarium and Pond Filter - Perfect Bio Balls for Aquarium Filter Media – Made in The USA OUTSTANDING FILTRATION! Each bio ball is covered in spines to dramatically increase the surface area of each ball providing space for a massive number of beneficial bacteria to colonize. These good bacteria break down harmful organic waste.  SUPERIOR BIO MEDIA: A huge problem with other bio balls 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 from poor water quality. TOUGH AND UNIQUE! Our bio balls’ spherical shape and precise spine placement permit them to pack tightly into any shape or filter type without losing surface area. Molded from high-density plastic, these balls are lightweight but tough enough to keep their shape and will never degrade or wear out. Bio balls can be used loosely or in a mesh bag with a plastic zipper. TRUSTED! Our Bio balls are 100% polypropylene making them reliable biological filtration media for fresh and saltwater. They are manufactured for use in koi ponds, freshwater fish tanks, saltwater aquariums, aquaponics, fish hatcheries, and much more. These 1” bio balls are perfect for the limited space of an aquarium sump. EASY TO CLEAN - If organic waste builds up in the bio balls, they can be gently rinsed in dechlorinated water to remove debris and refresh the bio balls. Use our FilterFirst, dual-density bonded filter pad, or water polishing pad to capture large particles to help keep your bio balls clean of debris.

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 bio balls.   RISK FREE! Does this come with a money back guarantee? YES!

FREQUENTLY ASKED QUESTIONS - Aquatic Experts Bio Balls with Mesh Bag  QUESTION: How easy is it to clean the bio balls? ANSWER: Typically you do not need to clean bio balls since most filters use a prefilter pad to remove most of the debris before water flows to the bio balls. In an  outside pond, bio balls may require cleaning. In this case it is best to take a bucket of water from your pond, and swish the balls around in this water to preserve the good bacteria attached to the surface of the bio balls.  QUESTION: How long should the bio balls last? ANSWER: Our Bio balls are made from high density plastic so they should never degrade or wear out.  QUESTION: I have a 1,000 gallon water garden pond. How many bio balls do I need? ANSWER: Typically, our 300 pack of bio balls will handle the bio-load of a typical stocked pond. With this said there are variables which effect how heavy a bio-load is in a pond including: how many fish, their size, how often they are fed, and so on. The only way to know if you have enough bio balls is to test your water for  ammonia or nitrites. If you detect ammonia or nitrite levels in your pond water ( not caused from overfeeding or a dead fish) add more bio balls.  QUESTION: Does your mesh bag have a metal or plastic zipper? ANSWER: Our mesh bag has a fish-safe plastic zipper.
