Overdosed AZ NO3

[Alentino]

My dad in m'sia added AZ NO3 over the main tank cuz i forgot to tell him to add it in sump. but he did follow the guidelines of dropping the different amounts day after day. now some fishes were showin some breathin difficulty and one just passed away i told him to stop the treatment. but what are the chances of other livestock surviving this? is AZ NO3 very potent?

You need a very powerful and effective skimmer to pair with AZ-NO3 treatment.

i have a big skimmer, it does look quite aggresive, but i'm worried that my dad screwed up the tank this time because he added directly to main tank. the skimmer is in the sump, blast it

i'm also a current user of az no3 and i feel that dosing it directly into the main tank shouldn't be that deadly. it looks like there's only a very marginal difference. i pour it into the sump, and within 3 seconds i think it'd have gotten into the main tank. surely that short period of dilution wouldn't be the difference bet. life and death?

[pospeh]

Its ok to dose in the main tank.

But as william said, you need a good skimmer to skim out the byproducts of the biological process, or else it wont work.

May i know what is az no3?

maybe u may wan to look into other causes ???

or it's just a psychologically feeling ???

AZ-NO3

The bacteria bloom caused by AzNO3 is depleting the oxygen in the water. Increase water circulation in the main tank and maybe drop in an airstone or two until the bacteria has been skimmed out.

Tanzy, there's no bacteria in AZNO but enzymes.

[Tanzy]

The enzymes causes bacteria growth that's why oxygen is used up and the water turns cloudy.

whew.... thanks so it was a case of oxygen competition after all, no wonder some fishes are gasping for air, but no worries anymore cuz everything is fine now and the skimmer does look alot dirtier than usual.
