Seachem Matrix Bio Media 1 Liter

I received a few different color media but they were mostly white. Theres a good amount of different sizes too. I filled up the filter and used the rest as substrate. It can be cleaned and reused so why not? It looks 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.

Bought for my aquariums to replace biomedia my filter came with. Along with regular partial water changes the ammonia and nitrites stay at 0 so no complaints here.

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 great for the fish tank.

This didnt do anything amazing or help out anything.

They use to be all the same size and all porous , now they mixed them with non-porous rock , even with shiny rocks just to add weight to the bottle wth?.

I read about Seachem Matrix and I thought I would give it a try. Great product and it really helped give my tank the bio boost that it needed to keep Ammonia and Nitrites at 0 ppm. I have Matrix media in a plastic canister in my extra slot on my Penguin 200, and after about two weeks or so the aquarium settled down and my numbers and levels got in line. I did have to tap some of the big stones with a hammer to make them smaller so they fit just right, but that was fine. UPDATE: 09/22/2012 - Seachem Matrix still wotking. Added it to a canister filter and Ammonia and Nitrites are at proper levels. All one needs to do periodically is give them a good rinse in aquarium water and place them back into the canister filter.

I bought this when I got my Eheim canister filter. The 1 liter bottle is the exact amount that I needed. Before I started using this stuff, I had minor issues with ammonia build up even with the bio sponges. Two weeks after I had this in my system, my ammonia and nitrites are at 0ppm and my plants pull out the rest of the nitrates with no problems. This stuff doesnt need to be replaced ever, so one bottle is all you need. Because this stuff holds onto all the good bacteria, you can feel free to replace all the other filter pads and such in your system without feeling guilty. Great stuff.

I have an adult RES male who if Im being honest didnt have a proper setup for a VERY long time. Ive been chipping away at investing in a better remainder of his life for him and this was a very nice thing to have! Ive been using it for about a year now and its really helped grow the bacteria needed to keep his water level stable and healthy. I havent needed to use much of it either, although I will probably be adding more soon!
