how to maintain nitrate nitrite and ammonia levels 0 in fish tank?

Answer 1

Keeping your ammonia/nitrites at 0 ppm is relatively easy in a properly cycled aquarium that has adequate filtration, is not over fed (especially with foods that have a lot of low quality ingredients that tend to pollute more), and with good aquarium husbandry procedures such as tank cleanings that do not "over clean" the aquarium such as complete water changes or washing of filter media or gravel in tap water.

Nitrates should be kept under 40-50 ppm. This is achieved in freshwater by water changes and healthy live plants.

Here are a few other steps for Nitrate reduction problems:
*Perform a water change using a gravel vacuum to remove not just dirty water, but “mulm” that will decompose and enter the nitrogen cycle and eventually become nitrates.
This can be a particular problem with Under Gravel Filters (UGF); decomposing organic debris will tend to build up under the filter plate. For these filters I recommend occasionally removing the lift tubes and placing a siphon into the opening and removing as much organic debris (mulm) as possible.
Even without UGF, poor vacuuming procedures (or none at all) can contribute to high to high nitrates. Make sure and vacuum around and under ornaments as well, although be careful around live plants.

*Proper filtration and maintenance; Make sure and regularly rinse in de-chlorinated or used aquarium water (never tap water) your bio filter media. This includes bio rings and balls commonly found in wet dry filters and canister filters, sponge filters, bio wheels, or any other media that is not changed in the filter. This is especially important with filters that tend to become “nitrate factories”, which include in my experience (AND tests) to be; Canister Filters, Wet-Dry filters, and Emperor Filters. This is not to say these filters are bad, it is just important to not ignore properly cleaning these filters even though their large capacity makes it very easy to do.
I have seen nitrates in freshwater go down by simply changing filter systems (the over all health of the aquarium improved as well). The last time I did this was by removing an Emperor 400 and replacing it with a combinations Sponge filter/ Internal filter/ Fluidized Filter System.

*Add aquatic plants to freshwater especially hornwort.

Ammonia Nitrite Nitrate

Answer 3

Make sure to perform partial water changes weekly to keep ammonia and nitrite levels at 0ppm. If the tank is new, you'll probably wait a minimum of 6 weeks before you have readings of 0ppm. New tanks go through a "cycling" process during which beneficial bacteria are colonizing. These bacteria "eat" the ammonia and nitrite eventually converting them in to nitrate.

Regarding nitrates, 0ppm isn't necessary. In fact, it can be nearly impossible to have 0 nitrates depending upon if you have plants, natural shells, driftwood and other organics that decompose. Nitrates are much less harmful to your fish than ammonia and nitrite so you should keep them down and they will be reduced by performing partial water changes.

Most of my tank's nitrate levels are at 20-30 and that is fine for my tanks.

Bottom line, water changes and vacuuming your tank's substrate is how you're going to keep your water parameters in check.

Answer 4

After your tank has cycled your ammonia and nitrite levels should stay at zero unless you are way over feeding or add to many fish at once. The only way to keep your nitrates down is through water changes.

Answer 5

Your tank has to go through the nitrogen cycle aka new tank syndrome. Ammonia will spike then turn into nitrites, then nitrites will spike and turn into nitrates. As long as your nitrates are between 0-.25 ppm, your tank will be fine to keep fish in. You want nitrates as low as possible. Live plants also help keep them down.

Answer 6

Water changes are the only way to successfully keep ammonia and nitrite at zero and keep nitrates low. If the tank has cycled there will always (and should be) some nitrates. Below 20 ppm is exceptable for most fish. For fish that are stressed or ill keep under 10 ppm. Under 10 ppm and the water is considered pristine.

Answer 7

Most definitely yes. For two reasons, Firstly as mentioned it emulates nature, which may induce fish to spawn or some sort of behaviour which is usually associated with rain, and the second is that the fish will grow bigger. This may sound odd, but fish give off chemical pheremones which are detected by the fish subconsciously, rather like a person registering a smell. The fish will grow according to the concentration, this is why a fish never outgrows it tank.... By doing partial water changes the chemical is diluted and the fish is fooled in to thinking it's in a bigger environment, it will therefore grow bigger

Answer 8

Water changes,cleanliness,if you want to have 0 Nitrates twice a week cleaning and careful feeding is important. You might also try to find material on a de-nitrating coil.

Answer 9

A good filteration system, water changes as needed, and a good diet for you fish. I never have problems with anyof these.
