Will Poly-Filter® sorb ammonia, nitrite and nitrate out
of fresh and marine water?
The Poly-Filter® sorbs ammonia and organic nitrogen compounds produced by fishes, invertebrates, sharks/rays, turtles and amphibians. The Poly-Filter® sorbs ammonia (NH3) > 0.10mg/L which only occurs above 7.5pH range. Below 7.0 pH mainly ammonium ions (NH4+) are produced which are nontoxic and nonsorbable by Poly-Filter®. Poly-Filter® can help prevent nitrite (NO2-) ions from reaching toxic levels through several methods. Poly-Filter® may sorb some nitrate (NO3-) ions in freshwater. In natural or synthetic seawater nitrate (NO3-) ions cannot be retained by any chemical filtration media due to sulfate ions leaching action. Anytime the sulfate ions exceed 40 mg/L this nitrate leaching back out of filter media is observed. Poly-Filter® sorbs many organic wastes that are converted into nitrates thereby lowering nitrate formation.
