The bio-medium is little volcanic-type rocks, large pea size. I’m using about half the container (250ml, so about 125ml). I’ve put the rocks into a bag, purchased separately, that fits my filter. My tank is 15 gallons and my filter runs at 200 gallons an hour (sounds crazy) so the rocks get a lot of flow. When I switched to this brand, I left my old bio-medium in the tank for about a week, so the bacteria would populate the new medium. My ammonia and nitrite are running at zero. I rinse the bag of rocks about once a week, scrubbing it between my hands to clear the algae. The rocks don’t get clogged, so I haven’t had to change them out for fresh ones. It takes time to build the bacteria population, and it’s important to keep something in your aquarium where the little creatures can live. In the photo, I’ve layered a bag of eggshells on top of the Matrix. (The eggshells raise the pH.)

I have only had this for a month or two, but after destroying our tanks eco system during an attempt to get rid of snails, it has been amazing. For several months, the ecosystem was struggling to cycle correctly. We lost several fish, one at a time, until this purchase. Since adding the Seachem Matrix, the water is clearer, the fish are more lively and colorful. Overall its a great product and maintenance is easy, just rinse rocks off and reuse.

Good works good

I like this stuff, its versatile and the pieces are a good size.

I purchased this for my saltwater fish quarantine tank to have some biological media that wont absorb medications if/when I need to dose them. This is one of the few products that wont absorb copper and is recommended for use in Saltwater quarantine systems. Would buy again.

I used since longtime looks like doing nothing. waste of time money and space in filter.

My African cichlids feel like they are home
