## Description

Matrix is a highly porous media designed to provide exceptionally efficient bio filtration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria. Each liter of Matrix provides over 160,000 cm2 (170 sq. ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media! This product is sold by volume. Cited weight is minimal weight. Matrix is a naturally mined, chemically inert material for facilitating the growth of biological filtration in aquarium and pond systems. Due to its organic nature - size, shape, coloration, and density of the Matrix material will vary slightly between packages. Any of these variants and small irregularities in sizing are perfectly natural and WILL NOT affect the integrity of the product OR its ability to maintain water quality. It will also not affect pH in the system.

Review: For Saltwater - Good for Tanks with Few Rocks - This is basically a very porous rock (pumice, I believe) that houses a lot of bacteria to process toxic Ammonia and Nitrites and (some) Nitrates. I considered buying pumice and using that instead but then you don't know what chemicals are used and this is fish tank safe so I went this route. I used this in my 29 gallon Aqueon saltwater tank in a hang on back Coralife Marine Filter with Protein Skimmer. It worked well and I had no issues with Ammonia and Nitrites. I used this in conjunction with Seachem Stability and added a clownfish from day 1 with no problems. I stopped using it though when I realized that I had enough porous rocks in my display to handle the bioload and repurposed the space in the hang on back for other things. Some people use this in a Quarantine tank but I think using a sponge and disposing is the safer route. I believe this is a solid product for Freshwater tanks and the larger pond version for larger tanks and ponds, but not as useful for Marine tanks with enough live rock. My batch came with some black obsidian and I emailed Seachem about it and they sent me a generous bag of Matrix to make up for it. Great customer support!
Review: Long lasting and good quality! - I added this in my canister filter in with the media that came with it, along with some purigen and my tank that had some issues getting my levels correct, cleared up quickly. My levels are and stay good now, as long I manage my water changes and cleanings pretty regular. It has helped cut my cleanings to every other week with 25% water changes. Love this stuff.

### ⭐⭐⭐⭐⭐ For Saltwater - Good for Tanks with Few Rocks

### ⭐⭐⭐⭐⭐ Has enough surface area to keep my turtle tank cycled
*by Z***R on June 13, 2014*

I use Matrix in my fish tanks, it does a great job. What is amazing is that it also works in my 55 gallon tank that holds two 6-inch red ear sliders. Turtles poop a lot! Some people say that a turtle tank can't be cycled, but mine is thanks to Matrix. I used the whole 500 mL bottle in my canister filter and I do 80% water changes once a week. Ammonia and nitrites stay at 0. Matrix is the best biological filter media out there.
