Seachem Matrix Carbon 500ml

Very high quality, low dust carbon.

As with most other Seachem products this one is no different. I am using this in my Fluval 307 canister filter for my 45 gallon freshwater aquarium. I have decided to go with this to save on spending money on the Fluval charcoal inserts. So far I have been pleased with the performance of this product. I am using nylon bags in my filter and I have had no problems.

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

Awesome

keeps my reef tank crystal clear.

Is this actual carbon? Doesnt release any dust...not sure how they pulled that off. It clarifies my water though, so will be buying again in future.

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

Added this in a mesh bag to my fluval spec 5 gallon tank. I got tired of paying 4$ for 3 of the fluval carbon replacements that I change every 3 weeks, and it works great

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

Exactly as described and worked as expected!
