How do I remove nitrate from my fish tank?
The simplest solution is a water change. When you remove a volume of water from your aquarium, you remove all the nitrate in that volume. So, change half the water and you’ve removed 50 percent of the nitrate.
What causes high nitrate levels in fish tank?
Nitrate levels build up in aquariums because it is the main by-product of the biological filtration process (Nitrogen cycle). Tap water can also have high Nitrate levels from agricultural run off.
How do you lower nitrate levels in 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.
