Greater than one weekFor the average fish tank owner ignorant to basic chemistry, this stuff is magic. For the enthusiast who knows how to at least titrate water parameters, this is your product. Per square inch of de-nitrifying bacteria colonization (internal and external) its the better cost effective product on the market. Plus like most Seachem products I use (Purigen, Phosguard, Cuprisorb); you never have to replace it. Perfect H2O!

> 3 dayI like this media and it fits nicely in my media basket, with some left over. Would be nice if it came with a bag though.

> 3 dayTruly AMAZING! My tank was cloudy for about two weeks. I was losing my mind with alternate solutions. I was told to try Matrix in my Fluval 306 canister filter. Overnight, my tank was crystal clear. I could not believe my eyes. Thank you Seachem, what an amazing product.

> 3 dayMatrix is the best biomedia out there, imo. I use it on my 5 gal planted betta tank. Lots of surface area due to its porous composition (lots of microscope images on Google), and you can pack a bunch of it into a small space. The pieces are about the size of small grapes, and with a little rinse to get rid of the dust, you pop em into your filter and forget about them until maintenance. I have 250mL of Matrix sitting in the back of my Fluval Spec V in a nylon media bag under the sponge that came with the tank. I have been fishless cycling for a few weeks, and my tank holds enough bacteria to easily process 3-4 PPM of ammonia in well under 24 hrs. Matrix works, and being a biomedia, it doesnt get easier or better than this. For all you Spec V and Spec III owners out there, I use this with the stock sponge (cut a bit off to shorten), stock ceramic media, and a 100mL bag of Purigen, and it keeps my water filtered and crystal clear.

> 3 dayI am a huge fan of Seachem products and this is just another favorite. I add a new bottle every 3 months to each cannister filter and it works great. Like the rest of their products its expensive.
