People often says to raise view and admire a fish, the heaviest if raise water, want to have good water quality only, fish ability health joy grows.

The knowledge that has development to water quality conduces to you becoming raise the person that had sufferred outstandingly, can make you avoid the happening of the problem, and when problem happening, try quickly to solve. The healthy problem of most after all fish comes from at abominable water quality, the article will introduce the most important water quality parameter to you, how to have a test, reach when water quality parameter is incorrect, how to amend.

Azotic loop

Azotic loop is the foundation of good water quality. It includes the parameter with 3 the most important facets: Ammonia Ammonia(NH3/4) , nitrite (NO2, ) with nitric acid salt (NO3, ) , in a healthy aquatic animals box, we try to let partial nitrogen cycle filtering undertake in the system. The following graphic representation shows the crucial level in the nitrogen cycle in aquatic animals box.

The crucial phase in nitrogen cycle

Nitrogen

(in air)

Food

Fish

Be eaten off by certain fish

The food that did not eat

Salt of use nitric acid is reduced

Agent or water quality balance fluid

Change water and take out plant is used through branchial ministry secretion

By microbial decompose

Nitric acid salt filters systematic ammonia

Nitrite

Ammonia and nitrite are right fish it is harmful. Filter the nitrogen cycle in the system happens, make ammonia and nitrite by salt of translate into nitric acid, and nitric acid salt is right most fish for basically hurtless. This process is called " biology filters " .

Ammonia and nitrite are taller in new aquarium. Be in likewise excessive jam or hello in feeding box of exceeding aquatic animals same also. If do not try to take seriously, chroma rises continuously, can bring about a disease to erupt, the fish dies only. Because this is fixed the test is very important. Otherwise although very clear aquatic animals case, likelihood ammonia and nitrite still very tall.

The test of ammonia and nitrite can use Tetra water quality to check an agent. Use easily simply, the state of instantaneous know water quality, below good position, the content of ammonia and nitrite should 0mg/l. If ammonia level rises,come 0.25mg/l. Or nitrite rises to 0.3mg/l. Should change water partly with dilute its chroma. Remember using already the water of purify chlorine, heavy metal, usable heart colour stabilizing agent of AquaSafe water quality.

In new aquatic animals case, ammonia and nitrite should everyday or two days have a test, in " mix raise model " in aquatic animals box, the test can decrease to every on Monday second.

Nitric acid salt is to happen in filter the biology in the system filters eventually child. It is to the fish it is opposite hurtless. Also be plant key raises one of shares. But, if do not have a test, excessive will be right fish create pressure, exciting algae grows, to most fish for, 50mg/l or lower content are ideal. Sensitive fish ask like 7 colour immortal lower density. You can have a test with reagent of salt of heart colour nitric acid. If chroma is exorbitant, can take the following step: Clean bottom is arenaceous, hello feed fecal little (absorptivity is tall) feed is like heart colour feed. Add many bits of plant, change water, or salt of use nitric acid reduces an agent to be like heart colour Nitrateminus. Total principle is every 2 weeks of examinations.
