## Overview

## Description

The Matrix is a highly porous media designed to provide highly efficient biofilfiltration for removing ammonia, nitrites and nitrates from freshwater, marine and coral aquariums in a single location. Over 160,000 cm2 (170 sq.ft) surface area per matrix, equivalent to over 40 liters (10 gallons) of typical plastic ball media! This product is sold individually. The quote weight is the smallest weight. Matrix is a naturally mined chemically inert material to promote growth of biofilfiltration in aquarium and pond. Because matrix is organic, size, shape, color and density may vary slightly from package to package. These variances and small irregularities in size are completely natural and will not affect the integrity and ability to maintain the water quality of the product. It also does not affect the pH inside the system.

Review: 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)
Review: 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!

*by A***R on March 18, 2023*

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.
