Seachem Matrix Carbon 500ml

After one week with the carbon the water became cristal clear

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

Kept aquarium looking pretty good

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

Works wonders in my large tank. Nice and clean.

Great

The carbon spheres are tiny. I tried to use them in one of my internal filters to remove some tannins out of my tank but since they’re so small, it fell right through the sponges and out of the filter grates. The space it the filter is limited so I can’t put it in a fine mesh media bag and shove that in the filter. I ended up having to cover the grates with filter floss so it wouldn’t fall out but that only means I’ll have to swap them out every time compared to using the sponges the filter came with. I’m sure seachem’s carbon is better than most but they really should make them in larger grain sizes

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.

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.

Good Carbon - Too bad Amazon DOUBLED the price since last month
