> 24 hourThis works amazing as a biomedia, probably the best. I do wish the rock chunks were smaller for my small sponge filters-- still very happy! They did take over 2 weeks to start up even though the tank and sponges were cycled for many months now, so just take that as a precaution.

> 24 hourI 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.

> 24 hourThe amount of media you get for the price is just ridiculous. Seachem seems to be getting greedier every year.

> 24 hourI had a problem with my ammonia levels. I tried several things to bring it down, to no avail. I bought matrix and after a few days my ammonia levels are back to 0. I now will never use anything else. Best in the world.
