MarinePure was originally launched in the UK in 2008 under the name ReefresH2O. The product was taken over by Cermedia in 2010.
There’s been quite a buzz about the MarinePure media since we debuted it at the UK trade industry show, GLEE, back in September 2008. With the recent review of the media in Marine World magazine this buzz has turned into an avalanche of enquiries and purchases, consequently I thought it was about time I put together some information about the product and the best way to utilise it.
MarinePure brings you a better way to keep your aquarium water clean through the use of Cell-Pore™ technology. With more surface area than other bio-media products, it gives beneficial bacteria more room to grow and enhance your aquarium’s capacity for biological filtration.
Its non-clogging, interconnected pore structure provides an efficient home for biofilms of aerobic and anaerobic bacteria to grow. Water is able to pass through quickly and easily, providing contact with both types of bacteria.
It mimics nature, providing the perfect balance of biological filtration, one of the most important factors in the health of your aquarium.
Importantly for marine systems, working in just the same way as natural products such as live rock,
Any closed environment accumulates waste from inhabitants, decomposing plants, uneaten food and other organic matter. An effective biological system uses beneficial bacteria to break down waste before it can become toxic to the aquarium’s inhabitants. These bacteria grow on surfaces as thin biofilms and need the right environment, depending on whether they are aerobic or anaerobic, to thrive – ReefresH2O provides those surfaces in both environments.
Aerobic bacteria change toxic ammonia to nitrites, and then into nitrates.
Anaerobic (denitrifying) bacteria change nitrates into free nitrogen gas and water.
The greater the surface area available for these two types of bacteria, the better the bioremediation of the aquarium system, since the total biomass produced is spread much thinner over all of this area, any tendency to clog is reduced.
Again, important for marine systems given the common problem of high levels of nitrates as a result of overstocking or of insufficient capacity for denitrification.
Products and Applications.
Currently MarinePure is available in a number of different forms:
• 1- 1/2” diameter spheres
• 8” x 8” x 1” plates
• 8” x 8” x 1” blocks
5/8” diameter spheres. Not in the MarinePure range. Limited quantities remain.
These small spheres are best suited to facilitating nitrification in freshwater aquaria, both tropical and coldwater.
Limited application in reef aquaria except as a substrate to provide a habitat for micro crustacea such as Gammarids.
Reported to have some utility when added to the rear compartment of nano aquaria such as the JBJ and D&D nano cubes.
Originally 1-1/4” diameter spheres – MarinePure now comes as 1-1/2″ spheres, increasing both surface area and capacity for de-nitrification.
These spheres are the same size as conventional bio-balls but have many times the surface area. Ideal for use in trickle towers where their fantastic surface area will facilitate extremely efficient nitrification. Aside from surface area these spheres bring an additional advantage in this application, in the event of a power failure their ability to retain moisture means that the bacteria will remain alive for a far longer time than would be the case when using plastic bio-balls. The water adsorption of MarinePure is such that it holds its own weight in water even after hours after draining.
If used in a low flow application where they are not subject to a flow of heavily aerated water these spheres will facilitate de-nitrification as their interior region will become anaerobic.
Keep a handful or so of these spheres in your sump and you have an instant filter available for adding to a quarantine tank for new fishes or for use with a hospital tank when medication is required that would be deleterious to live rock.
A single bacterially live sphere added to a shipping bag will make for a safer way of moving livestock. Although do be aware of the importance of using a bag of sufficient size to ensure the fish isn’t forced into contact with the media. May not be suitable in this application for use with some substrate dwelling fishes.
Originally 9” x 9” x 1” plates – MarinePure comes as 8″ x 8″ x 1″ owing to improved manufacturing technology.
The 9” x 9” x 1” plates are very versatile. When placed in a high flow area of oxygenated (aerated) water, these plates will provide an excellent substrate for the nitrification of ammonia and nitrite. In addition, these highly versatile plates (like their larger counter parts, the 9” x 9” x 4” blocks) will facilitate passive de-nitrification. For the best de-nitrification, place these plates in an area of gentle to low water flow, keep them out of the flow of heavily aerated water and do not use in a position where water would flow rapidly through the plate.
Use in place of a sand or gravel substrate on the base of the aquarium. If you’re nervous about placing live rock directly on the glass the plates will spread the load at the same time as providing de-nitrification. For aesthetics I’d suggest using a sacrificial layer of sand, just a thin scattering to cover the plates, which can then be periodically syphoned out along with accumulated detritus.
The plates are very easy to cut, I’ve used what I believe to be a tile saw for this job, and can be used in a similar way to egg crate to create ledges and shelves for supporting rockwork. If desired small holes can be drilled through the plates to enable structures to be tied together using nylon electrical cable ties.
“Top Tip – use black cable ties in preference to white or coloured cable ones as they seem to be more resistant to UV hence last much longer.”
Using plates vertically against the back or sides of the reef aquarium provides you with a great substrate for corals to grow on, this way you can get away from seeing all that glass and have corals growing all the way to the water line without having to build a water displacing rock wall.
Originally 9” x 9” x 4” blocks – MarinePure comes as 8″ x 8″ x 4″ owing to improved manufacturing technology.
The blocks are the most efficient way of facilitating de-nitrification. Simply place in an area of your sump where the block is subject to a gentle to low water flow. Make sure to keep it out of the flow of heavily aerated water and avoid any position where water would be forced to flow through the block too quickly. A slow, consistent flow of nitrate laden water through these blocks allows sufficient time to create the ideal anaerobic environment necessary for de-nitrification to take place and for waste products (nitrogen gas and carbon dioxide) to be efficiently carried away.
Depending on the size of your aquarium, the quantity, and size of your fishes, and the amount of food you feed, multiple blocks can be used to control the nitrate level of your water. Some customers in the States have seen as much as a 2 gram reduction in nitrate-nitrogen levels per block per day when used in this “passive” format.
Coral frag plugs. Not in the MarinePure range. Limited quantities remain.
Like the rest of the product range, the frag plugs are made of the same foamed ceramic material, but at a slightly higher density. This means that, when mounting a coral frag to grow-on, you have the advantage that it can adsorb nutrients from the aquarium water in a the same way it would in the natural reef environment. When a frag starts growing onto the plug from it’s initial point of glued attachment (we recommend Reef Gel for this job) the porous nature of the substrate results in faster plating out than is seen when using a non-porous material, especially plastic or concrete plugs.
The improved growth is mainly due to the porosity of the frag plug allowing nutrition to reach the growing base of the coral.
Unlike coral plugs bonded with conventional Portland cement, there’s no danger of experiencing a high pH spike when using MarinePure frag plugs. MarinePure propagation plugs arrive sterile from the ceramic firing process and are ready to use without any post cure or conditioning.
