PRO-4-DJ RODI MARINE FISH TANK REVERSE OSMOSIS WATER FILTERS RO DI FILTER

Replacement Reverse Osmosis Rodi Water Filter Packs To Suit Our Fish Tank Reverse Osmosis Water Filters - Pro-4-Dj / Pro-4Dj + Ron-4-Dj Models

Select replacement filters required from the drop down menus
 
If you need instructions on how to change these filters send us a message when checking out and we'll include them.


Standard volume pre-filters can used for up to +/- 10,000 litres of RO DI water produced and the high volume Matrikx CTO filter will be able to produce +/- 35,000 litres [based on typical town water and includes waste water].

Membrane flow is rated in GPD [gallons per day] at 55psi so on average membranes produce at the following flow rates: 50GPD = 8 Litres Per Hour, 75GPD = 12LPH, 100GPD = 18LPH and 180GPD = 28LPH.

The Pentek 100GPD TLC membrane is a new generation membrane that has a higher rejection rate [98%] versus standard TFC membranes [96%] and the Pentek TLC membrane can deal with feed water TDS levels up to 4x what standard membranes can and you can download the Pentek TLC performance data sheet here.

Comes standard with either a pre-filled DI Resin Cartridge or loose resin to refill your filter cartridge, as selected. If you want to purchase extra resin to refill that cartridge select 1x or 2x Loose DI Resin Refill from the drop down menu. If you want to purchase an extra cartridge that is pre-filled, select DI Resin Cartridge from the drop down. 


We have a separate listing where you can purchase larger quantities of loose DI Resin here

Our resin is the highest food grade mixed bed deionising resin and is supplied loose so you can refill your existing refillable in filter cartridge or in a refillable filter cartridge [let us know if you want a white or clear cartridge or we'll dispatch according to stock levels].

All of the parts that come into contact with the water in our systems are manufactured from BPA free food grade plastics. All of the filters and parts that we source are of the highest quality and meet the required quality standards.

Not all the images displayed in this listing are included in the item for sale as images of other related items are included for informative purposes only but available in our online store and the last image is of the type of system these filters fit.

If you are not entirely satisfied with your purchase please contact us so that we can try to resolve your concerns.

Water comes out with 0.0 ppm of nitrate and 0.0 ppm of phosphate for at least 1000l of water produced - great for the reef tank :)
