The bottom line: this set is for aquarists who need a high surface-area ceramic media to seed beneficial bacteria and improve biological filtration; the single biggest reason to buy is the large quantity of porous ceramic blocks that provide ample colonization area at a low cost. The reviewer found the media to be well made from a porous ore and volcanic ash blend and especially useful when you need to fill large sump trays or DIY canister chambers.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous material:\u003c\/strong\u003e The ceramic blocks are made from porous ore and refined volcanic ash to offer a large internal surface for bacteria to colonize, improving nitrification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh surface area:\u003c\/strong\u003e Each block is covered with thousands of tiny pores, providing extensive area for biological filtration compared with smooth media.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-action filtration:\u003c\/strong\u003e The highly porous ceramic delivers both mechanical trapping of debris and biological adsorption of impurities, helping to clarify water.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomizable size:\u003c\/strong\u003e Blocks can be cracked into smaller pieces, so users can adapt the media to different filter chambers, sumps, planted tanks or ponds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBulk quantity:\u003c\/strong\u003e The box contains 108 pcs sized 3.8 x 1 x 1 in, which is convenient for larger tanks, multiple filters or seasonal pond maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis ceramic bio media is best for freshwater aquarium hobbyists, planted tank owners and koi pond keepers who need an affordable way to increase biological filtration capacity.
