Matrix, 4 L / 1 gal.

I have used Seachem Matrix for well over a year now, and I can say for a fact that it is by far the best media out there, and the results I have had using it prove it. Every bio media will give your filter the surface area to grow aerobic beneficial bacteria that convert ammonia and nitrites into nitrates. What's so special about Matrix is that each piece of the bio media is so porous yet dense that there are nooks and crannies in each piece that a special type of beneficial bacteria is able to grow, specifically anaerobic bacteria. This anaerobic bacteria consumes nitrates. This type of beneficial bacteria is one that can only grow in environments that are not oxygenated (which is why the porosity and nooks and crannies Matrix bring to the table are important). I keep African Cichlids (Mbuna specifically), which have a reputation for being some of the most demanding fish when it comes to bio load. I keep the tank stocked moderately, overfiltered, and chalked full of as much Seachem matrix as I can fit. Before switching to Matrix I was using the typical ceramic rings and doing weekly water changes. My Nitrates would get up to 30-40 PPM after 1 week with no ammonia and no nitrites. After switching to Seachem Matrix and giving the anaerobic beneficial bacteria a couple months to establish itself, it is a night and day difference. I test my water weekly. I was shocked to begin seeing a decline in the numbers on my nitrate tests. Probably around the 6 month mark or so, there began to be such a little amount of nitrates that I could skip water changes. I keep everything recorded in a spreadsheet and there was one point that I went 2.5 weeks without a water change and my nitrates were only at 25 PPM, KEEP IN MIND THESE ARE FULL SIZE MBUNA WITH NO PLANTS IN THE TANK. I still do weekly water changes and test my water weekly, but typically there is so little nitrates that it wont even register on a dip test strip and API registers between 0 and 5 PPM. Truly amazing. The proof is in the pudding, Seachem Matrix makes big claims and much like every other Seachem product, it backs them up. 10/10 would recommend, I will never run another bio media in any tank.

I’ve been using Matrix for around ten years. It works extremely well, and holds up over time. I do keep it in mesh bags inside of my filters. I can’t imagine cleaning a filter without using the mesh bag, for easy removal and rinsing. I’ve been working on a new garden pond and decided to give matrix a go in place of the commonly used lava rock. Clearly a large amount is needed so I started price hunting these 1 gallon matrix tubs. This was the best priced I found. I like to buy from my LFS but the price was nearly double. Everything arrived in perfect condition, and as expected.

Excellent filter media. I used two gallons of this media in my new setup and it helped with my water quality and allowed for the quick addition of fish.

Matrix is a high-porosity biological filter media designed for aquarium filtration. Matrix has a vast internal pore network that provides surface area for the attachment of beneficial bacteria. Porosity and high surface area alone should be the measure of biomedia. Matrix has a primarily macroporous internal pore structure. This means the pores are large enough for the bacteria to enter and form stable colonies. Large surface area measurements sound impressive but if the pores are too small the bacteria cannot get in and colonize the media. This means the bacteria can only grow on the unprotected surface of the biomedia. The colonies are vulnerable to washout caused by high velocity “microshear,†which is the scrubbing effect of water flowing over smooth surfaces. Seachem Matrix protects nitrifying bacteria inside the porous network so the colonies remain undisturbed. But there’s more. Under the right conditions natural denitrification can occur, lowering nitrate levels without the need for a special de-nitrification filter. Matrix provides the right microenvironment that allows nitrification and natural denitrification to take place in the same filter. Seachem Matrix will remove ammonia, nitrite and nitrate! Matrix can be used in any power filter, canister filter, contactor or filter sump. Matrix never needs replacing and can be rinsed if it becomes dirty.

I purchased the 1 gallon sized Matrix due to the cost savings when split with a friend. We each got 2L of Matrix for our canister filters. This filter media works very well. My water is clear. My water tests all show good values, with no signs of ammonia, nitrate or nitrites. All fish are happy and thriving. My planted tank is looking great! I can't say how this will work over years, but for the last 2.5 months, this has been doing its job and the fish are all thriving. Maintenance thus far has been a bi-weekly rinse out of my filter sponges, and for the first time, a quick shake and rinse of the basket full of Matrix. I didn't scrub or do anything to remove more than the loose sludge that was sitting on the media. My sense is the less you do in disturbing the good bacteria, the better. Just need to clean out the gunk to allow for good water flow. I had some extra and added it to my son's 3 gallon tank filter. I can't say it's changed the world, but I would think it's helping in keeping those fish happy too.

Excelente producto, siempre de una gran calidad, cumple con la descripción de la publicación.

Product arrived as described. Very little powder and very few garbage stones. My thermo 600 took all x4l. Will update x4 months from now on performance changes. Replaced ceramic rings and sintered glass bio balls from Ehiem. Make sure u wash thoroughly and soak for 24hrs to keep the floaters to a min. Update; working well in my 600, all my values are 0 and the water is crystal clear with just a little yellow due to wood in tank. All x4l went into my 600, flow is good with the 45ppi ring sponges on pre filter. Taken x7 weeks for these results. PH is stable at 7 to 7.1 Great stuff but still expensive!

未開封で有る事を示す物は無く画像通りの開け閉め出来るバケツで届く。 なので気になる人は重量チェックする事をお勧めする。 又中の埃(チリ)が酷いのでマスクしてから開封及び洗浄した方が良い(群馬の某通販の比では無いほど相当シェイクされている)

Köpte detta då det skulle fungera mot Nitrit vilket inte mycket gör. Har 2 filter ett JBL 1900e på mitt 720L akvarium och ett Aquael 2000 på mitt 450L + några filter till på dessa. Efter ca 4 månader hade jag knappt någon nitrit alls inför vattenbytet jag gör var 14 dag. Innan var Nitrit halten strax under 50 nu under 20. Bra produkt som gör det den lovar med ge den lite tid att etablera rätt bakterieflora.

قوي فعال وحجمه كبير ويكفي لي اكثر عن فلتر خارجي كبير يكفي لي فلترين او ثلاثه على حسب الحجم
