300 Count Bio Ball Filter Media with Mesh Bag - 1.5 Inch Large  OUTSTANDING FILTRATION! Each bio ball is covered in spines to dramatically increase the surface area of each ball to nearly 2 square feet providing space for a massive number of beneficial bacteria to colonize. These good bacteria break down harmful organic waste keeping your aquatic friends safe. You will receive approximately 300 1-1/2-inch bio balls in a mesh bag. Just rinse and use.   TOUGH AND UNIQUE! Our bio balls’ spherical shape and precise spine placement permits 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 loose or in the mesh bag with plastic zipper.   TRUSTED! Our Bio balls are 100% polypropylene making them a safe reliable biological filtration media for fresh and saltwater. They are manufactured for use in koi and water garden ponds, freshwater fish tanks, saltwater aquariums, aquaponics, fish hatcheries and much more.   SUPERIOR TO LAVA ROCK: Over time, porous lava rock becomes clogged with d 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 bio balls.   RISK FREE! Does this come with a money back guarantee? YES! Your purchase comes with a full 90 day no-risk, no-nonsense 100% Money Back Guarantee. Either you're thrilled, or we don't want your money! 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.

  3.0 lbs - Premium Activated Carbon Aquarium Filter Charcoal Media - Remove odors SUPERIOR PERFORMANCE! Our premium carbon has been super cleaned and is hungry to rapidly trap contaminants and toxins from your aquarium water. This is great for you because you will have a clearer, odor free aquarium while the exceptional water quality will help your aquatic friends thrive. BREAKTHROUGH! A huge problem with other aquarium activated carbon is that the pores are packed with ash that a simple rinse will not wash away; these pores should be clear and clean. This problem is solved with our carbon! How? After heat activation, our carbon goes through a rigorous cleaning to deep clean the pores. You never have to suffer buying unclean carbon. ELIMINATES ODOR AND DISCOLORATION! Our activated carbon, also known as activated charcoal, removes foul odors from aquarium water leaving a crisp clean smell. Our active carbon has large internal surface area which rapidly adsorbs dissolved pollutants from water including yellow-brown tint, toxins, chlorine, most medications, and some heavy metals. Our Premium carbon works best in our Fine Mesh Filter Media Bags (included) or similar bag. CLEANER AND LAST LONGER! When rinsing typical carbon everything can get covered in black dust including your hands and sink. Our premium carbon makes rinsing easy since we clean and wash out a majority of the dust and fines. What makes our carbon last longer is our exclusive cleaning opens up large surface areas inside each granule allowing it to trap more organic compounds. CARBON INSTRUCTIONSFor best results, use our FINE MESH MEDIA BAG. Simply add 1/2 cup per 40 gallons of aquarium water.  FREQUENTLY ASKED QUESTIONS - Premium Activated Carbon QUESTION: This carbon is tiny does it require a special mesh media bag? ANSWER: Yes, it requires a very fine mesh media bag. You can use our Fine Mesh Filter Media Drawstring Bags or a similar tiny mesh bag option. QUESTION: Why does your carbon have moisture in the bottle? ANSWER: Our premium carbon goes through a cleaning solution to remove trapped ash, then through a final cleaning bath. After this, most of thewater is drained and the product is packaged to ensure freshness. QUESTION: Why does your premium carbon weigh more than similar size containers? ANSWER: Our premium carbon is intentionally crushed to a small size to allow for greater surface area. The smaller fragments pack tighter leaving lessgaps compared to larger carbon pieces. Additional weight is the result of some moisture left over from the special cleaning baths. QUESTION: Is it necessary to rinse your carbon? ANSWER: Yes, during shipment carbon pieces rub against each other and may produce dust. A short rinse under tap or RO water will rinse away this dust.

Many hobbyists have both 100 and 200 micron filter socks which allow them to swap out their 200-micron socks from time to time.Q: How often should I change the filter socks?A: It depends on the tank load, but generally you want to change your filter socks once a week or every two weeks. The more often you change your filter socks, the better your water quality; it removes organic solids before they have a chance to further break down.Q: Is it better to use a longer sock with more socks hanging in the filtered water than a shorter one?A: Ideally the filter sock should be hanging in the water without touching or laying on the bottom of the sump. If a shorter sock is above the water line there may be more noise as water drains from the sock side and splashes into the water In your sump.Q: Is there a glaze finish on these filter socks? the glaze makes them less flexible and stiffer. or are they untreated?A: Our socks are untreated. The felt is soft, flexible, and perfect for trapping floating debris from the water.Q: Has anyone verified if Aquatic Experts filter socks will work with the reefer?A: We have personally tested Our filter socks in the reefer sliding shelf sock holder. Our filter sock material is thick and our plastic ring is slightly too large to drop through the hole in the shelf.Q: What makes Aquatic Experts felt filter socks better than any other brand?A: Owning an aquarium store and service company for 25 years meant that we had to test countless filter socks to find the best ones. One stood above the rest giving consistent and repeatable filtration performance in freshwater, saltwater, and reef tanks.
