Seachem Matrix Carbon 500ml

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 .

Well, i change the review of this product because I mistakingly with other product that I bought, I put the Seachem Carbon in the nylon bag and put into hang on filter which help to clear the water on my 30 gallons salt water tank, so far i dont have any fish or coral going bad yet, I just have the tank 3 months, with 10 fish in cluding 1 copperband butterfly, ( i know it ricky for 30 gal tank but sofar the fish still beautiful and actively) several damsel,and cloud fishes.

Excellent performance.

Larger granules than other brands. Good quality product.

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.

What I expected

Excellent aquarium carbon media.

Great carbon. Best I have used in years. Lasts about a month, depending on your flow rate. Highly recommended. Costs a but more, but its worth it.

Awesome

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