Seachem Matrix Carbon 500ml

It clears my tank fast and removes toxins for a long time.

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.

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

Great product

The product came open or that is without the protection seal as I have always received it. And it was missing carbon inside. it came in half the bottle.

Im not sure if its the shape of it or if its the purity or whatever ,but i used just a couple teaspoons for a very cloudy 5 gallon and it was clear in 45 minutes. Ive used other activated charcoal before any this one seems to be much more efficient .

Product works perfect and just as described. I highly recomend this product for any fish tank along with some purigen.

Best carbon I have used but its finer grain size makes using it in a flow through media necessary. I put a about 4 ounces in a 180 micron mesh bag and place it in each cannister filter. I change it every 3 weeks and it does fantastic.

Larger granules than other brands. Good quality product.

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.
