Nitrate

issit true if there isnt any trace of nitrate..there will be no nitric or ammonia in da water??..thanks in advance.

not entirely, there may be nitrite.

I would recommend testing for all.

Nitro Cycle - Ammonia --> Nitrite--> Nitrate

Simplified Nitro Cycle:-

Fish Shit- produces- > Ammonia --> Nitrite--> Nitrate

So, if there;s no ammonia then your fish is not shitting coz its not been feed?

Hi Faxtor,

In a tank where there's detectable level of nitrate, it shows that there's some form of nitrification going on.

However, this does not mean that other forms of nitrogenous waste compound is absent.

If ammonia release into the water is faster than the nitrifying bacteria can cope, then there may be a back log of ammonia and nitrite present.

Though nitrate is not as toxic as ammonia and nitrite, it can also reaches a level that can be toxic to the nitrifying bacteria colony. I cannot remember the specific toxic nitrate level for these BB off hand, but I think it should be 80ppm or above.

When nitrate reaches a toxic level for these BB, then they would die back. As a result of a decrease BB numbers, naturally there'll be an accumulation of ammonia and nitrite. This is a phenomena call incomplete nitrification.

Cheers,

Kenny

(ps I suppose bio-waste cultivate BB in some way but too much bio-wate eventually result in cloudy water, rite? perhap by adding plant in the tank a little)

Hi Jeff,

Well, yes, indirectly perhaps.

the cloudy water usually comes from a quick proliferation of bacteria in the water, in the presence of ammonia, which is their 'food'.

Different types of bacteria would have different toxic threshold to the nitrogenous waste level, and thus even if a certain level kills the BB colonies, other bacteria may thrive in them.

Adding plant is not a viable option, if you do not provide a coducive environment for them to thrive and help remove nitrogenous waste product.

Aquatic plants would have required a good amt of lighting and CO2 to thrive. Those that don;t require too much light and can live w/o CO2 injection, would be slow growers and will not remove those waste as fast.

Cheers,

Kenny

It also indicates that your system has no BB

thanks alot gain something today

Dear Kenny,

I have been testing the water amidst frequent water changes. ammonia and nitrite is negligible if not present. However nitrate is constantly above 50 or 100 ppm. I am using probiotic bacteria 21 which does efficient for ammonia and nitrite. also i have placed the aro in the planted tank in covered in a lawn of riccia. Is any other further action required.

cheers
