External filters are an excellent option for medium sized aquariums and upwards. Their large size and power means they are the most suitable option for larger aquariums, or those that are heavily stocked or house messy fish which produce a lot of waste. Excellent for aquariums housing large and/or big groups of cichlids, carnivorous fish species, oddballs, stingrays etc. They are also a great option for those who wish to invest a bit more in a filtration system in order to cut back on aquarium maintenance. A larger filter means larger surface area for beneficial bacteria which means more waste can be broken down. Being an external filter there is no large unit that sits inside the aquarium itself, just some intake and outlet pipes, this makes it easier to create a more natural aquascape and also gives your fish more room to swim! It is worth remembering the clean out your filter impellor regularly in order to keep your filter working to its full potential.
Ocean Free's new Filtron series of canister filters connect the brand's Hydra-Pure technology with a new 4-stage water purification system.
Hydra Filtron’s 4-Stage Water Purification, goes beyond the conventional 3 stage filtration (Mechanical, Biological, Chemical), with the incorporation of the revolutionary Hydro-Pure technology that uses Hydroxyl Radicals (OH) to accelerate the startup time from the usual 4-5 weeks to within 1 week, reduce water odour, and retain a crystal clear tank.
It is the first canister filter in the world to incorporate Hydro-Pure Technology (cata-pure) into its design.
Key Features
4 Stage Filtration Process
The first stage breaks down large solids and traps suspended particles, the 3DM nuggest provides a high surface area for beneficial bacteria which helps break-down toxic waste (e.g. Ammonia and Nitrites) biologically. In stage 2 the BioTrap Sponge breaks down finer solids and traps suspended particles and also provides a surface area for beneficial bacteria for further biological purification of toxic waste. In stage 3 the Fine Filter Wool removes fine particles, and the Carbon Pad absorbs dissolved organic compound and heavy metals to maximize the efficiency of the Hydro-pure Technology. Stage 4 incorporates Hydro-Pure technology
Uses Hydro-Pure Technology (Cata-Pure)
The Hydra Filtron Filter is no normal external filter. Using Hydro-Pure technology that is capable of enhancing the natural filtration processes in aquariums by as much as 50% when compared to conventional systems. With the help of the Cata-Pure Cartridge, the traditional nitrogen cycle is sped up as several stages are bypassed and unnecessary. It consists of two electro-plates to energize a cartridge box containing special Cata-pure Catalyst Media to generate strong reactive Hydroxyl radicals (•OH), which is the key to the detoxifying and depurating reactions process.
These filters are quick and easy to install, the one pull priming will quickly fill the unit with water and make it ready to use. They come fully supplied with all the filter media and a valve for easy maintenance.
