I am selling my custom made nitrate filter due to my move to marines from freshwater. There is no other product like this on the market I can assure you.
The filter uses 14L of purolite 520E ion exchange resin. This is a commercial product used in water plants which is not available to the public. What makes this product unique is that it operates at hose pipe speed 500l/h unlike other nitrate filters which are trickle speed only. The resin takes my tap water of 45ppm nitrate down to 0 and would last for 8000-10000 litres before it would need regenerating. If you have lower levels of nitrate from your supply it would last a lot longer. Yes this commercial resin can be regenerated 1000's of times with a 15% salt solution without loss of capacity making it a life time product for hobbyist or even commercial use (would be perfect for a fish shop or big systems).
This resin does not effect any other elements of water chemistry which makes it so good.
