Seachem Matrix Bio Media 250ml

It should take a while to know how well it works

Best media for planted tanks

This stuff is great for housing beneficial bacteria, I only use this, and Purigen in my filiters!

Nice sizes, light weight, very porous. My go to bio filtration media.

Good product at a good price.

Truly AMAZING! My tank was cloudy for about two weeks. I was losing my mind with alternate solutions. I was told to try Matrix in my Fluval 306 canister filter. Overnight, my tank was crystal clear. I could not believe my eyes. Thank you Seachem, what an amazing product.

Trying to keep my goldfish tank crystal clear has been a challenge in my slightly overstocked tank dispite keeping NO3 and NO2 on the high side of normal. I have been doing full water changes every month and have tried variety of filtration medias and charcoal products. I decided to try this in my Tetra HOB fiter. I placed the rocks in the open spaces of the plastic bio filter. You could see it improving the water clarity day by day until the water was clear.

I like this stuff, its versatile and the pieces are a good size.

Make sure you get a mesh bag for these. Im not sure why it doesnt come with one. I had it clog the water intake for the propeller motor on my canister filter. Some of the rocks are like pebbles and will float around and may cause you issues. I took it out and Im probably not gonna use it. Its not really nessecary.

I really like these they feel like good quality and look and feel very pourus. My water parameters have been good so I think its safe to assume these are working. Also its seachem, their known for reliable products.
