Matrix, 500 mL /17 oz

I added this in my canister filter in with the media that came with it, along with some purigen and my tank that had some issues getting my levels correct, cleared up quickly. My levels are and stay good now, as long I manage my water changes and cleanings pretty regular. It has helped cut my cleanings to every other week with 25% water changes. Love this stuff.

This is basically a very porous rock (pumice, I believe) that houses a lot of bacteria to process toxic Ammonia and Nitrites and (some) Nitrates. I considered buying pumice and using that instead but then you don't know what chemicals are used and this is fish tank safe so I went this route. I used this in my 29 gallon Aqueon saltwater tank in a hang on back Coralife Marine Filter with Protein Skimmer. It worked well and I had no issues with Ammonia and Nitrites. I used this in conjunction with Seachem Stability and added a clownfish from day 1 with no problems. I stopped using it though when I realized that I had enough porous rocks in my display to handle the bioload and repurposed the space in the hang on back for other things. Some people use this in a Quarantine tank but I think using a sponge and disposing is the safer route. I believe this is a solid product for Freshwater tanks and the larger pond version for larger tanks and ponds, but not as useful for Marine tanks with enough live rock. My batch came with some black obsidian and I emailed Seachem about it and they sent me a generous bag of Matrix to make up for it. Great customer support!

So after experimenting with matrix for years for nitrate reduction this is what I have found: it will reduce nitrates to zero if enough is used until some clogging occurs. Then it will reduce to a point which is still better than traditional ceramics and such but not to zero anymore. Still keeps water changes on my 40 gallon to once a month and the nitrates don’t go above 30-40ppm. In an African cichlid tank using fluval rings vs matrix the matrix kept tank at 60ppm and the rings went linearly up until water change ie did nothing. So it’s better than other products but nothing can stop nitrates once they get clogged. Rinsing the media brings back nitrate reduction capacity but again only until they clog during the month.

Great product. I had a 14 gallon bio cube and tossed the bio balls and replaced it with matrix. After cycling the tank I added about ten mollies. I had two unexpected batches of mollies from other tanks and after a few weeks I put the fry into the biocube as well so that I had about 30 fish in total almost 2/3 of them were juvenile. Way overstocked! After two weeks I went to do a water change and was sure that I would find ammonia and nitrites through the roof. But I was quite surprised that ammonia and nitrites were negligible. I'm replacing all the ceramic tubes and bio balls and other media in all my other tanks with Matrix!

I use Matrix in my fish tanks, it does a great job. What is amazing is that it also works in my 55 gallon tank that holds two 6-inch red ear sliders. Turtles poop a lot! Some people say that a turtle tank can't be cycled, but mine is thanks to Matrix. I used the whole 500 mL bottle in my canister filter and I do 80% water changes once a week. Ammonia and nitrites stay at 0. Matrix is the best biological filter media out there.

Best biological filtration that I've used. Does what it says it will do.

I can not praise Matrix enough. I use Aqua Clear (now branded Fluval) HOB filters and used to use the ceramic media they came with. After switching to Matrix my long battle with fluxuating Nitrites finally ended. I had been having trouble for over a year. All my tanks use Matrix as the biological now. I highly recommend it for everyone, novice to expert! No product on the market comes close.

I'm not sure whether it was my water changes or this product that lowered my nitrates by 20ppm. I think both.

My fish tank have the water clean after i use this material

Seachem Matrix is an outstanding bio media that has greatly improved the filtration in my aquarium. Its porous structure provides excellent surface area for beneficial bacteria, ensuring stable water parameters. Since adding it, I've noticed clearer water and healthier fish. A must-have for any aquarium enthusiast looking for efficient and long-lasting filtration.
