Seachem Matrix Carbon 500ml

I use it for a month and then rinse it out real well with fresh water and its ready to go for another month. Use it on my saltwater aquarium and does a god job.

This is a great product although this is the first time I am using it. I used to use activated carbon that comes with filter refills. Matrix carbon is much superior in performance and delivers better results. I have a bio filter submersed in the tank ( not a bio filter in the mechanical filter).

Excellent aquarium carbon media.

Exactly as described and worked as expected!

high quality product

works better and longer than cheap carbon from the pet store. I use this, along with seachem purigen to keep my tanks crystal clean. nothing but the best for my turtles

This stuff is great! Instead of cylindrical bars or chunks of carbon, this is tiny beads of carbon. Rinses clear in seconds with very little dust particles. You dont need much either, half a cup for 50 gallons or so. I used to have to fill a mesh bag to get the same effects as this stuff.

do know if it is working any better than any other biological media but I would buy the pond matrix because it had alot of small pebbles in it

Awsome product, using it for few years now. Helps to keep water clear.

Larger granules than other brands. Good quality product.
