Seachem Matrix Carbon 500ml

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.

Wow definitely notice the difference from regular carbon and this. Cheaper on Amazon than my local fish and let stores. Definitely recommend Ive switched to Seachem everything for my mediums and water additives.

Well 1st I dont run carbon all that often, but over the years I have found that only 2 brands really do a better job at least in my tanks. If you need to remove resudule meds or other impurities Seachem Matrix Carbon is the way to go. Toss it in a aquarium mesh bag put it in your filter.

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

Great product

Everyone says this is the best carbon....and they are right!

Although not the cheapest choice in active carbon i belive its by far the best choice and all i will use in my reef system, lowest phosphorus levels of any carbon , spearical shape allows for better flow as well as more surface area also due to spherical shape. Keeps my water spotless and safe for critters, i like to change every 2 weeks as i feel as it still may be working in my 100 gallon its mostly exhausted .

What I expected

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

Item came in half of the bottle. Not sealed.
