Nitrate Resin 25L

Product Information
An ultimate weapon against blanket weed! Unique nitrate selective ion exchange resin which only removes nitrate! Even when the nitrate level is very low, no other substances which could lower the pH value (like calcium sulphate) are removed. This in comparison with other nitrate resins, which are known for years in the aquarium world. Operation: the nitrate ions are exchanged against harmless chloride ions.

Advantages of this resin against conventional resins for nitrate removers:
1) High capacity, even at high sulphate concentrations
2) Amount of sulphate ions in the water remain at the same level
3) No significant change in the pH value
4) Easy to regenerate with NaCl (table salt).

Dosage: 1 litre resin can remove 30 GRAMS/litre nitrate.

The resin can easily be regenerated with NaCl (200 grams of table salt per litre of resin) if the resin is saturated with nitrate.

An example on nitrate production: 10 kilos of fish wet weight, 0,1 kilos food dry weight each day (based on food with a 50% protein content) produces 8 gr. of TAN (Total Ammonia Nitrogen) dry weight per day. In a aerobic biological filter 1 gram of Ammonia converts 3,3 gr. of Nitrite, which converts to 4,4 gr. Nitrate. Multiplied by the 8 gr. of Ammonia, mentioned above, we have 35,2 gr. Nitrate per 100 gr. of food. Please note: actual figures will depend on type of filter and filter media and water quality.

Application: fill a mesh bag with nitrate resin and then place the bag in the biological filter so that the water passes through it completely or put it in a separate filter house and let the water run through it in a by-pass with a flow of ± 5000 liters/hour. The lifespan of the resin is about 15 years but by means of organic pollution of the porous resin the actual lifespan will be around 5 years. The lifespan can be extended by regenerating the resin once a year in a hot saltwater solution (50°C).
