Review on Enhance Your Aquarium's Filtration with Fluval Biomax Filter Media by Mariah Garrett

This is truly amazing value. Ceramic filter media, like everything else in life, varies widely in quality. Fluval Biomax is incredibly porous because it is not buffed or polished. It's rough texture and millions of tiny crevices attract nitrifying bacteria like a magnet and encourage rapid growth. Because they are so textured and allow full water flow, colonization is very fast and you will see the results of this product in less ammonia. Spikes, as well as more stable water parameters. At this price, they're a lot more expensive, plus they're eligible for Prime, so throw in free shipping to boot. I suggest ordering more than you think you will need - remember to rinse them in aquarium water, not tap water. The same applies to filter maintenance: always rinse the filter material with water from the tank that services the filter. This protects any healthy bacteria and removes dirt. Using tap water will kill your colonization on contact. While Fluval claims to replace them every six months, I can assure you that after 40 years of keeping fish, it's just a matter of selling more product. In fact, ceramic substrates last almost indefinitely, so they rarely need to be replaced. They are also great for filling a new aquarium filter and reducing cycle time. Eheim broken glass aside, this is one of the best mediums to use - a great product at an incredibly big discount.
