How do you lower nitrates in a freshwater aquarium?

Water changes: Performing regular water changes with water that has little or no nitrate will lower the overall nitrate level in the aquarium. If your local tap or well water is high in nitrate, using deionized water (DI) or reverse osmosis water (RO) can help keep nitrate levels low when doing a water change.

What filter removes nitrates?

Reverse osmosis
Reverse osmosis is one of the most powerful methods of residential water filtration and is able to reduce over 98\% of waterborne contaminants. Generally speaking, reverse osmosis can specifically remove anywhere from 83-92\% of nitrates.

Why is my aquarium nitrate so high?

Overfeeding is the number-one cause of high nitrate levels in aquariums. Overfed fish produce much more waste than normal, and when more food is given than they can take in, the uneaten food rots and produces even more wastes. Keeping too many fish in a tank also leads to problems with accumulated wastes.

How do you lower nitrates naturally?

What can we do to aid in the removal of nitrates from the aquarium?

1. Add live plants to a freshwater aquarium. Plants naturally utilize nitrate as a nutrient and food.
2. Reduce fish population or upgrade to bigger tank.
3. Cut back on feeding.
4. Use a nitrate remover such as ALGONE.

Can a water filter remove nitrates?

Nitrates can be removed from water by reverse osmosis, distillation, or through ion exchange resin. Nitrates will not be removed by sediment filters, carbon filters, or by the hollow fiber membrane of an ultrafiltration system. Similarly, a traditional ion exchange water softener will not reduce or remove nitrates.

Does distilling water remove nitrates?

Nitrate may be successfully removed from water using treatment processes such as ion exchange, distillation, and reverse osmosis. Heating or boiling your water will not remove nitrate.
