Seachem Matrix Carbon 500ml

Every Seachem product Ive ever bought has some form of tamper seal. Even Matrix Carbon Ive bought in the past. First bottle has no tamper seal, replacement bottle was the same, both covered in carbon reside on the outside of the bottles. So dont know if Seachem changed their packing practices for Matrix Carbon or what the issue is. I however wouldnt use any product in my aquarium that doesnt have a tamper seal on it. Seachem is great overall but cant give this anything other then 1 star because of the condition it arrived in.

Works amazing. Great deal on Amazon, costs 3x as much anywhere else. BEST carbon out there.

These are fine, too fine for many uses. The small granular pieces are small for my filter.

This is much cheaper than buying individual bags of charcoal. I bought the little bags here on Amazon and now all I have to do is fill them with carbon and replace the carbon monthly. This is so much more economical than buying pre-packaged carbon.

The size of the carbon is perfect for my reusable filter cartridges. It doesnt slip out of the slots!

Rinses fast and lasts a long time. Running in my Fluval G3 FW 55g. Water is crystal clear.

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.

keeps my reef tank crystal clear.

Excellent aquarium carbon media.

This replaced my regular carbon. My regular carbon lasts a month matrix is still in there over a month. Keeping my water orderless and free of a leaky piece of Driftwood.
