Six Stage RO/DI Aquarium System with 50/75/100 GPD Membrane. Dual DI REFILLABLE Color Changing Media Cartridges. ALL CLEAR HOUSINGS.


Reverse Osmosis systems, combined with A DI after filter, will give you the lowest TDS reading for your aquarium water supply. DI Resin is necessary to reduce Total Dissolved Solids (TDS) to zero and is the last stage of an RO/DI unit. It is unnecessary to use the expensive proprietary DI cartridges that other RO manufacturers sell. Simply buy a refillable DI cartridge and fill with DI resin. You'll save money and get the same results. 


A constant supply of high purity water can be obtained by using two cartridges in series and allowing the first cartridge to completely depleted. During this operation, the second cartridge ensures that the water leaving the system is of the highest purity. New cartridges are placed into the polishing position and the remaining cartridge is put into the “roughing” position. This ensures complete utilization of all the exchange capacity, which lowers operating costs while increasing average quality.

 

The clear cartridges are refillable, so you can save with buying media in bulk, and using the inline cartridges again, and again.  We use Resintech MBD 30 DI resin.

Our 6 Stage Reverse Osmosis filter consists of the following:

1st Stage - All of our sediment filters use multi-gradient spun polypropylene filter cartridges. These cartridges use the entire depth of their media by trapping the largest sediment particles on the outside of the filter, then gradually stepping down the size of particles they will reject as the water moves closer to the core of the filter. The result is longer filter life, greater dirt-holding capacity, higher flow rates, and remarkably low pressure drop. The 100% pure polypropylene media is highly resistant to bacteria and chemicals, making this an excellent choice for both well water and municipal water treatment applications.

 

2nd Stage - Carbon is a substance that has a long history of being used to absorb impurities and is perhaps the most powerful absorbent known to man. One pound of carbon contains a surface area of roughly 125 acres and can absorb literally thousands of different chemicals. Activated carbon which has a slight electro-positive charge added to it, making it even more attractive to chemicals and impurities. As the water passes over the positively charged carbon surface, the negative ions of the of the contaminants are drawn to the surface of the carbon granules. With carbon block filters, water is forced through the pores of the densely compacted carbon block, where a combination of mechanical filtration, electrokinetic adsorption, and physical/ chemical adsorption take place to reduce a wide range of contaminants.

3rd Stage - Solid Carbon Block technology can reduce chlorine, taste and odor problems, particulate matter, and a wide range of contaminants of health concern -- cysts (cryptosporidium and giardia), VOCs (pesticides, herbicides, and chemicals), certain endocrine disrupters, Trihalomethanes (cancer-causing disinfection by-products), heavy metals (lead, mercury), turbidity, MTBE, Chloramines and asbestos. Solid carbon block filters do not remove healthful, naturally-occurring minerals.
