Marlin PRO - Perfect for any Aquarium / Pet Store or Coral Farm

Looking for an awesome filtration system for your aquarium, reptile or pet store? Or, do you have a monster-size tank at home and your current RO/DI system is just not cutting it? 

Check out our Marlin PRO that reliably makes up to 1,000GPD and can tackle just about any water issue and will provide amazing and healthy water for all the animals under your care. 

Each Marlin Pro is hand-built in our Winter Park, Florida facility. Filtration starts with a monster 10x54” Up-flow Carbon Tower filled with our Chloramine Blaster Carbon. Not only is the Chloramine Blaster Carbon perfect for dealing with chloramines issues, this medical-grade carbon is also better at removing chlorine, pesticides, VOC’s, THMs and other unwanted chemicals.  

With most of the unwanted chemicals removed, water then passes through three sediment filters: a 20-micron pleated sediment filter to remove larger particulates, then two 1-micron poly-blown sediment filters to remove any remaining sediments, sand, dirt, rust, silt and sand. The pleated sediment filter is washable and can be reused up to 5 times to save you money. 


The next step is the heart of the filtration system: the reverse osmosis membrane. Our commercial RO membranes are made in the USA with a stabilized salt rejection rate of 98.6% ! With a heavy-duty commercial-grade booster pump providing all the water and pressure for the RO membrane to work efficiently, the system will reliably produce up to 1,000 gallons of ultra-pure water in a 24 hour period. 

The final stage is the twin Deionization filters. Each 20” refillable filter cartridge is filled with our, made-in-the-USA, color-changing mixed-bed DI resin. We only use nuclear-grade, virgin, DI resin  that is never regenerated resin. The cartridges are also packed fresh when your system is built so you get the maximum performance and life out of the resin.  

Commercial-grade solenoid and high, low pressure switches are installed to make operation as easy as possible. A glycerin-filled pressure gauge lets you monitor system performance and a back-lit Triple TDS Meter helps monitor water purity.  


Our Blue Marlin systems have been providing many aquarium / pet stores across the country with clean, purified, water for many years. Many reef aquarium stores and coral farms rely on the great quality water that our system produces. We also offer the best after-sale support and the technical engineering knowledge and experience to help you with any water issues.
