Seachem Matrix Bio Media 250ml

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.

I am a huge fan of Seachem products and this is just another favorite. I add a new bottle every 3 months to each cannister filter and it works great. Like the rest of their products its expensive.

This stuff is great! No more buying those overpriced Aqueon filters.

I had a problem with my ammonia levels. I tried several things to bring it down, to no avail. I bought matrix and after a few days my ammonia levels are back to 0. I now will never use anything else. Best in the world.

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

bottle came in smaller than i expected.. i recommend getting the 500ml

It may not be the most surface area per cubic inch. Compared to newer products on the market. But its been time-tested. Its cheaper and easy to use ... No worries about leaching aluminum or other metals.

Use this media in all of my hob, canister, all in one/built in filters. Also used it in place of/in addition to live rock in frag tanks.

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

I bought based on good reviews. Ive only started using for 2 weeks; so time will tell. Im running in media bag for 30 gallons.
