0 Nitrogen

Looks like I might have a problem with low or no nitrogen in my planted tank
(CO2 injected); currently tested Ammonia, Nitrite and Nitrare as 0 (Aquarium
Pharm test kit), some of the plants that take N from the water column such
as Limnophilia Aquatica is suffering (lower leaves are browning off), even
the Anubias are starting to look yellow in the older leaves. The fish load
in my 280L is still low at the moment, as I'm basing carrying capacity based
on expected fish sizes (currently 5 SAEs, 13 Ottos, 18 Cardinals, 12 Rummy
noses and 6 Congos). Besides feeding them more (and also getting more
phosphates and possible getting algae), any suggestions, as N appears to be
the limiting factor here? Does anyone know of a source of Potassium Nitrate
in Sydney?

Cheers,
Poe

Poe,
I know I was able to find it on eBay here in the US. But there might be
problems shipping it international. Couldn't hurt to look into that though.

Good luck,
Ron

That's actually what I did, as well as do a search on Google, and phone
several hydroponics places (all had pre-mixed stuff)...

You might be able to order salpetre ( "saltpeter" in US English) in a pharmacy. Saltpetre
is plain just plain potassium nitrate. I got some that way.

I've also found another suggestion here :

Thanks; I can get it from chemical supply companies, but at 500g at a time
(when 50g will probably last me a year or two...).

May try my local butcher or chemist.

Poe

Hiya Poe,

Have you tried asking your local pharmacy? I ask my local chemist (in
Pymble) to order in pure chemicals and they look it up and order it.
Sometimes they ask why I need it.


Regards
Graham.

I ended up doing that at my local chemist (coincidentally he had just place
an ordere for some for sausage making); I could actually order from the
suppliers, but didn't want 500g, when I only needed at most 100g for the
next 2-3 years.

Cheers,
Poe

Unfortunately we don't accept any butt remover of the actinic blazon in the hardware food if I checked. Ended up acclimation some via a chemist who coincidentally bare some anyhow for meat preparation. I anticipate it's quite difficult to access potassium nitrate actuality due to its potentially explosive nature.

Becoming a passionate blogger, I’m happy to determine other men and women taking gumption and adding on the neighborhood. I just

desired to remark to display my understanding for a submit because it is especially inviting, and lots of writers do not get the credit
