Will lesser water speed up the tanl cycle

[Hebaodan]

Hi Guys I am a new arowana keeper, would like to find out more on the tank cycling process as my ammonia have been high for the pass one week at 4ppm, nitrite is at 0.25 -.0.5. will reducing the amount of water in the tank speed up the cycling process and make the bio filter work better? than slow adding aged water day by day till the tank is full again?

My currently tank is 300 litre with one AVFSR, ehiem 2075 canister filter, 2 airstone with baby high blow, a pack of coral stone and a drift wood with water plant on it.

Please advise me. thanks.

My advise is to never rush the cycling of your tank...

you should complete the cycling before adding fishes.
Since the fish is in the tank now, I guess you can only let the tank cycle itself and try to keep water conditions up for the fish.

no, lower water level does not speed up cycling. on the other hand, if the water volume is low and you are feeding a fixed amount of food regularly, ammonium concentration will be higher.

What I would suggest you to do is to do more frequent water change now to keep ammonium and nitrite concentrations down and wait out for biological filtration to sort itself out.

try not to increase fish population for now until the biological filtration is fixed.

reduced feeding may help to keep ammonium concentration down, but at the same time, you might be depriving the arowana of food. So, just feed what is sufficient, dont overfeed.

Hi All, thanks for your reply.

Actually I am currently training my aro on pellet diet therefore it has not been eating for the pass 4 days. will my aro immune systems drop due to lack of food and suffer from ammonia poisoning more? Anyway I do add seachem prime every alternate day even without water change will this help?

stressful condition is going to reduce its immunity against diseases.
high concentrations of ammonium and nitrite in water are toxic to living things. and the toxicity is one of the reason to cause stress to the fish.
prolonged lack of food may cause stress too.

no, adding chemicals without water change isn't going to remove ammonium. some chemicals do bind out the ammonium ions into non toxic forms, but that does not remove the ammonium. the problem is not removed, it is just delayed.

in a regular fish tank, the 2 major ways to remove ammonium are through nitrification by bacteria or water change.

Hi! Perhaps you can try bottled nitrifying bacteria aka fast cycle aquarium products.

Hi Dave

Thanks for your well info.
So will 50% water change every alternate day be enough?
Will water reduce the BB and hence causing the cycling process to slow down?
Also I heard the adding aquarium salt helps to reduce the toxic level of ammonia and nitrite? is that true?

Hi Nookie83

I do add seachem stability for the past 10 days and I add the OF 10k bacteria that is in powder form but still does not show any fast result.

Ts, be patient with the cycling process.

Honest, adding this & that will further add stress to the new aro.

Hi Streetsmart73

I understand where you coming from. But now I am trying to find more ways to reduce the damage "If possible" as the aro is in the tank and I cant remove it.
