      Is "K1" a name brand? Where to buy?

      I've done lots of searches and I'm getting a bit confused about "K1" media. Is "K1" a brand name, or is it a "type" or "measurement"?

      I found lots of K1 media online, only to find it then being described as MBBR or something else. Is "K1" a brand name? Is this all still considered to be "K1", just because of its shape and size, or are these knock-offs trying to compete with a brand name?

      Where's the cheapest place to buy this stuff? It all seems pretty darn expensive to buy in bulk. I'm in Phoenix, if that helps.

      Also, some sites advertise per liter, others by grams or kilograms or something else. What the heck. I shouldn't have to use a conversion calculator each time I search between sites.
      Ideally I'd like to find about 150 liters, or 5 to 6 cubic feet.

      It's actually both. K1 is a brand name used by Evolution Aqua but also designates the size of the media. For instance K3 is similar but larger. See this link http://evolutionaqua.com/acatalog/K1_Media.html

      Knock-off media is also fairly common and I suspect it is just as good but at a lower price as your not paying for the name brand.

      The name is Kaldnes (Evolution Aqua Kaldnes K1 Filter Media).

      German designed Mutag biochips are an alternative MBBR media with a far higher surface area (5000m2/m3) vs K1 (500m2/m3).

      15l of this media would have the same surface area as 150l of K1.

      Biochips.... interesting, but seemingly unobtainable. Even the manufacturer's web site doesn't say where you can get them. No matter, I'm sure they're beyond my budget.

      They sell for about US$10 a liter here in Singapore. I didn't realize how hard they were to get other places.
      They're supposedly used in our (in)famous sewage to drinking water treatment plants, which is possibly why they are easier to get here.

      They are quite a bit more expensive per unit mass, but are cheaper when you consider that you need only a fraction of the quantity.
      This in turn means a much smaller reactor vessel (or more room for increasing MBBR capacity if the need arises)

      The real genuine Kaldnes K1 or the cheaper knock-off media?
      I am not suggesting that the real K1 is any better.

      $10 a liter is for Mutag biochips.

      Kaldnes K1 here costs about $110 ffor a 50 litre bag. The farm I get my koi from is the official EA distributor.

      Knock off stuff is a lot cheaper. I'd bomb the heck out of those with PP though. I got some for a small aquarium before, and they reeked of mold release agent or whatever gives plastic that sweetish smell. EA K1 has no almost no odor out of the bag.

      I believe you should buy the larger size... it is easier to keep contained, from escaping.
