Seachem Matrix Bio Media 250ml

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.

Best filter media by far. Get a media bag!

I bought this and I dont see much results. I think Im going back to the usual dark charcoal filters.

I used since longtime looks like doing nothing. waste of time money and space in filter.

came in this little bottle very misleading

I dont have numbers or proof but I use this as my biological media with sponges. Many people swear by it so that is why I chose it. Natural as well.

I have used this in my 125 gal reef tank for two years in a 5 stage canister filter. I have two 304B canister filters and one of them is just totally full of this and it is working wonders for my tank! One of the best purchases I have made since Ive been in the saltwater/reefing hobby.

I like this media and it fits nicely in my media basket, with some left over. Would be nice if it came with a bag though.

Es tan bueno que espero 4 libras que compre espero me regalen una muestra gratis de algo que manejen

Lo mejor que eh comprado para mi filtro. exellente inversion lo recomiendo
