MarinePure® is the perfect place for beneficial bacteria to thrive, leading to the best water conditions for your pets.

Reptiles and amphibians need clean water. Protein and waste breaks down into toxic ammonia which causes many unfortunate health conditions including burning of gills or causing harmful skin conditions.

MarinePure’s bio-media is the most technically advanced bio-media available today:
> Features Thin Bio-Film Technology™
> MarinePure is inert and will not harm tank inhabitants
> Has been proven to significantly contribute to the overall health of the system

Why Use MarinePure®?

  • All pet owners have a goal of creating a healthy living environment for their pet
  • For those who own amphibians, aquatic or semi-aquatic reptiles, this means having excellent biological filtration
  • MarinePure® Biofilter Media maintains a stable and safe aquatic environment

Which MarinePure to Use?

  • The system you choose will depend on the size of the tank, how man gallons of water and precise care requirements for your pet
  • There are several shapes and sizes to fit your needs
  • Head over to our blog to see what those recommendations are
  • Head over to our product page to see their details

Thin Bio-Film Technology™

The combination of vast surface area and open/interconnected pores allows a thin bio-film to develop. This thin film allows bacteria to flourish because necessary nutrients are immediately available. With the open pores, old dead bio-film is easily flushed from the media and will not plug the media. Water flows through the media, not around as with other denser medias, thus utilizing the most surface area for beneficial bacterial growth.

MarinePure® Technical Info

MarinePure is designed to be a substrate for bio-filtration, specifically to target ammonia and nitrite removal (nitrification) and to minimize nitrates (denitrification). MarinePure biofilter media’s unique combination of vast surface area and open-flow porosity make it the most unique and highest capacity biofilter media available. Water can access the entirety of the structure allowing the bio-film to remain thin and ultimately more viable.


Read on for the commonly asked questions about MarinePure…

What makes MarinePure® bio-media unique?

MarinePure’s unique combination of open porosity and high surface area, allows a large number of beneficial bacteria to easily access nutrients (ammonia, nitrite, and nitrate). The Nitrogen Cycle can be efficiently controlled.

Why is a bio-filter important?

Ammonia and nitrite are very harmful to fish and must be eliminated. A properly operating bio-filter will result in low levels of both.  In the case of MarinePure and other deep porosity media’s, they will also help control Nitrates

What is Thin Bio-Film Technology and what does it mean to me?

The open porosity and vast surface area of MarinePure means healthier bacteria colonies. Clogging is minimized due to the nearly infinite number of paths through the media.

How is MarinePure different from plastic biomedia?

It comes down to available surface area for bacteria growth. MarinePure has 1000 times more surface area than plastic media. With greater surface area, the supporting bacteria growth is thinner, allowing efficient transfer of nutrients. Your filter and pump components can be greatly downsized saving money. MarinePure will also stay wet longer if in the case water flow stops or the media is removed from the filter, allowing the bacteria colony to stay alive longer. Using MarinePure will make a healthier environment for your livestock that is easier to maintain.

How much MarinePure media should I use?

Each system is different because of bio-loads, flow rates, and results desired.  Contact Cermedia to discuss how MarinePure can be used your project.

I know MarinePure is effective at removing Ammonia and Nitrites, but will it remove Nitrates?

MarinePure bio-filter media does an excellent job in supporting bacteria which remove ammonia and nitrite. Bacteria based Nitrate removal is a little more difficult as it is very system dependent. Any media for this purpose needs to contain an anoxic environment (very low oxygen) and have a carbon source available. These conditions are dependent on the systems bio-loads and flow rates. Our media, with its deep interconnection pores allows oxygen in the water passing through the media to be consumed.  The interior of the media, or smaller localized regions, can harbor the bacteria that change Nitrates to Nitrogen gas. We recommend placing the media in a passive or low flow area for the best opportunity to remove Nitrates.

Will your media become clogged like other medias?

Due to the open pore structure water flows easily through the media and particles are less likely to become trapped. The Thin Bio-Film Technology found in MarinePure allows a thinner film to develop, which, when it sloughs off, is easily flushed. As with all bio-medias, we do recommend a mechanical filter in front of all bio-medias in any flow-through filter design.

Can MarinePure be used directly in the tank or pond?

Yes, MarinePure can pe placed in mesh bags, or baskets, and locate throughout the pond.  Contact Cermedia for more information.

What is MarinePure made of, and will it leach anything into my water?

MarinePure is an inert aluminosilicate ceramic that has been fired (at) over 1000°C. It will not leach into the water.

What about cycling? Will MarinePure cycle faster?

While MarinePure is the most effective bio-media on the market, it is still the bacteria that does the work. The bacteria needs time to grow and multiply. MarinePure, with its open porosity, will be the most effective media allowing efficient transfer of nutrients to the bacteria.

Is a mechanical filter needed?

With any flow through (active) bio-filter, mechanical filtration is recommended before the bio-media to remove any solid fish waste, organic debris, and uneaten food.

Where is MarinePure made?

MarinePure is proudly made in Buffalo, NY since 2010.

I’ve been told MarinePure is expensive – why should I spend the money?

If you calculate the cost per surface area of our media versus others on the market, you will see MarinePure is actually more cost effective. It is designed to last for many years, as some competing products recommend changing as often as yearly or less! In large scale situations, due to the reduced size of filters and pumps, and reduced water changes, the cost savings of using MarinePure can be significant.

Does MarinePure plug up and how do I clean it?

If used in an active filtration system, we do recommend good mechanical filtration in front of the media and your media will resist plugging.  If you do need to clean the media to remove built-up detritus, a quick rinse in a container with system water will do the job. It can also be cleaned and sterilized using a 7% hydrogen peroxide solution, soaked overnight, if necessary.
