What causes high nitrates in aquarium?
Detritus, decaying plant material, dirty filters, over-feeding, and overstocking the aquarium all contribute to increased levels of nitrate. Additionally, tap water used to fill the aquarium may contain nitrate in it. In the United States, drinking water may have nitrates as high as 40 parts per million (ppm).
What is the fastest way to lower nitrites in a freshwater aquarium?
- Complete a 25% water change and retest after a few hours.
- Add Fast Filter Start to boost the natural bacteria in your filter to process the extra nitrite.
- Support the health of your fish using Aquilibrium First Aid Salt.
- Continue to regularly test your water.
What removes nitrates from water?
Ion exchange units, reverse osmosis, or distillation all remove nitrate from drinking water. Note that boiling water does not remove nitrates and is not a treatment alternative. In fact, it increases nitrate concentrations as water evaporates. An ion exchange unit operates much like a household water softener.
