Nitrates are good when are used in industry and agriculture; the are bad as pollutants of soils and waters.
No nitrates are not needed.Mainly CO2 and water is needed
Ammonia, nitrates, nitrites
Amines + Nitrates/Nitrites = carcinogenic nitrosamines
- absorbing nitrates from soil by the roots- for some plants fixing nitrogen with the help of bacteria
Yes, the nitrates in smoked meat can be bad for you. It is said that these nitrates can cause cancer at times.
Nitrates are a fertilizer, so when nitrates hit a pond or stream, the plants there could overtake and drain all the oxygen out of all the plants, so the plants will die. The animals living there are also affected, because for example, fish in the water could die if a water hyacinth gets nitrates because the fish in the water will not get any sunlight.
More often than not it the larger fish in your tank, check your PH and nitrates.
In a marine REEF aquarium nitrates should be kept as close to 0 ppm as possible. In a fish only marine aquarium you should strive to keep your nitrates below 20 ppm.
As soon as nitrates have reached zero. Don't ever change more than 20% water a week. If you have fish in the tank during the cycling process you will need to change some water if the nitrates are in the deadly range to keep your fish alive. Otherwise I recommend an additive such as Prime to keep nitrates from killing fish during cycling.
Fin rot. You will need to test your water and make sure that it's ammonia, nitrates, and nitrates are at 0, you have filtration, change your water, and then buy it some antibiotics from the fish store.
Fish bladder disease is an incurable genetic disease but a fish can live a happy life with it. However, certain factors can exaggerate the effects of the disease including a poor diet and poor water quality. Constipation is a major cause and can be cured by not feeding your fish for a few days or if your fish is an omnivore, it can be fed greens like green peas or romaine lettuce. High levels of nitrates are also a cause. Test your water for nitrates. Work on eliminating nitrates by adding live aquatic plants that feed on nitrates as well as doing regular water changes.
Because Chile sends the US copper, fish, fruit, paper, iron ore, Nitrates, wood pulp, and processed fish.
Nitrates are good when are used in industry and agriculture; the are bad as pollutants of soils and waters.
If the questions is what is the waste product of freshwater fish, then that would be ammonia. Freshwater fish product ammonia which is excreted through their gills and into their water, to keep this poisen to a minimum you need to a filter which has bacterial build up in the media which lives on ammonia and converts it into nitrite, then another group of bacteria absorb nitrite and product nitrates. Nitrates are much less dangerous to fish and some of them are used up by plants so planted tanks are much healthier for fish nitrates however do need to be kept low and weekly water changes should do that effectively.
They provide hiding places for the fish, they will take in Nitrates completing the Nitrogen cycle, and they look nice!
