Seachem Matrix Bio Media 1 Liter

I added wood to the inside of my aquarium. The wood leaked tannins into the water and turned it brown. I added this along with charcoal filters to one of my two filters and it pulled and keeps pulling the tannins out. The other benefit is more surface area for helpful bacteria.

I’m so glad I bought this it literally saves so much time and it’s true to holding bacteria for aquariums set ups

This brand is good for the price

I brought this matrix along with fluval biomax rings months ago. I put them together in a corner box filter and man oh man do these things clean! I have an overstocked 10 gallon fish tank and the matrix along with the bio max rings keep the tank clean! Protip: if you have a box filter put this, fluval biomax rings, and polyfill together in it. You'll have the ultimate filter! Plus, you save money too!

Using Prime with (3) 45% water change, and adding Matrix to the filter at the start. The spike was eliminated with in 2 days. The water was a bit cloudy, but on the 4 day the water looks crystal clear.

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.

Excelente

Put them in my canister filter. Also have them in a hob filter. I like them.

Bon

Prodotto di ottima qualità, con una grandissima capacità di filtrazione biologica. I materiali sono ben realizzati e si integrano perfettamente nel filtro, contribuendo a mantenere l’acqua pulita e stabile. Lo sto utilizzando con grande soddisfazione: ottimo rapporto qualità-prezzo e una soluzione che consiglio assolutamente a chi vuole migliorare la filtrazione biologica del proprio acquario.

good stuff...does what it says on the box....been using it for years!

主人の水槽の濾過材に購入。入れるだけ綺麗になり、とても良いです。

It came unsealed. Some of the bottles weighs lesser than the other bottles..not too sure on the authenticity of the product.
