Seachem Matrix Bio Media 1 Liter

This is great for the fish tank.

In all my many years of keeping fish, many have claimed to have products to bring down nitrate levels, but none worked. This is the first product I have found that actually does. And it is cheap. I did use it in my canister filters as opposed to hob, after reading the reviews. Seems some had mixed results that way. But I am amazed at the results I have gotten. It is not immediate, it took some weeks to see it drop, but after two weeks out Im at 10 ppm. Will buy again.

Llego exactamente como me lo imagine y todavía me sobro para llenar dos bolsitas más de Matrix y les cuento mi filtro es de 60 a 100 galones porque mi pecera es de 100 y el filtro es de los filtros que son afuera y perfectamente me cupo el matrix con la bolsita de purigen lo que hice fue poner el matrix en bolsillo de terciopelo o las bolsitas donde se pone el carbón activado y encima del matrix puse el purigen obvio encima pero que el agua lo mantenga mojado ya que el purigen si se seca se daña el matrix aunque se seque siempre va a funcionar y como el purigen dice que el agua tiene que pasar a través de el pues así mismo hice y todo va bien el agua se puso un poco blanca pero investigue y es en lo que las bacterias se adhieren al matrix y les cuento yo enguaje el matrix antes de ponerlo en el filtro definitivamente lo voy a volver a comprar

This is my first time using this media and I just put it in the filters so it would take some time to know the effectiveness. I bought couple of 1 L Seachem matrix bio bottles, and very consistently, each 1 L bottle has about 1/5 to 1/4 of other rocks. Seachem needs some better quality control here. I cant believe that several reviewers said they only had a few other rocks. For the dust, they were not too bad, I only had to put them in the sink and rinsed a few times.

This is in fact large enough to not need a media bag when used in a canister filter. With that being said I think it would be better to use a media bag to make it easier to take it out to lightly rinse if it gets too dirty, also will make it easier to reposition. This is a very good product, the bacteria grows rapidly on it and it is the only thing I use on my 120 gallon as far as bio media. I use 1 and a half times the amount suggested and all my parameters are perfect. I also use Purigen to remove organics from the water along with my protein skimmer. I also would recommend that when you put Matrix in you should pour some bio boosting bacteria on it to help kick start the growing process.

I use this in my fluval fx4 and it’s great

After reading the feedback from other buyers I can only say Ive lucked up with receiving a full bottle. By no means am I as experienced in the hobby as everyone else so I may not know about the actual performance of this product but through reading I do expect to enjoy some benefits from this.

I have used this for a while and it works as advertised. My goal was to get my aquariums to be as low maintenance as possible. So i did tons of research and found that bio-media is the most effective way to keep aquarium water at the right parameters. I now use this, purigen and filter floss and my water is not only crystal clear, but also perfect paramaters. My ph is always around 7-7.5 0 nitrates and nitrates and 0 ammonia! I do add water when the tank gets slightly lower and do a 25% water change every couple months! I couldnt ask for a better, low maintenance aquarium! I use this on a 29 gallon angelfish tank as well as a 60 gallon community tank.

Great filter medium. Can be added to a hang on the back type filter or canister filter. Much more surface area for beneficial bacteria than ceramic bio rings or plastic bio balls.

This product is well known for being excellent at providing a place for beneficial bacteria to grow and flourish. It is not overly expensive so I got some and added it to one tray in my cannister filter. It, along with a tray that has a bioball/ceramic ring combo makes up the bulk of my biological filtration with a large coarse sponge pre-filter helping also. This should be more than enough to handle my 75 gallon tank. I also have some sponge media for mechanical filtration but I like to rinse these with tap water so that the bacteria multiplies where I want it and not on the sponge that will eventually get replaced. The only issues I have are 1. There is at least half of this that is very dense like a rock. It is not all porous. That is not a deal breaker because I want bacteria growing in different ways and hopefully I will attract different types. 2. This really does need a bag to hold it. It will work in the cannister but the smaller pieces move and get wedged under the tray handles preventing it all from stacking correctly. I fit this into two media bags and this just makes it easier to clean but you will need to purchase a bag. Overall, based on reputation alone this is worth having in a tray. There is enough porous rock to justify the cost and now I have a nice diverse set of media in my filter working 24 hours a day.
