    This 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.

    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.

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

    Dusty at first. Give it a good rinse, pop it in your filter, and youre ready to go!

    I 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.
