Think twice if you are still planning to buy from overseas or to stock up KNO3!
It's controlled here in the USA at larger volumes, do not fret.
They just take your name, ask what you are using it for etc.
Of course KNO3 is terrible for making bombs but gas and kerosene are great....but they put KNO3 on the list too due mostly to ignorance.And we never used KNO3 to make our bombs in camp... It's usually petrol or kerosine...
And we all know why they do not put gas on the list
Such laws will not stop anyone wanting to make a bomb.
It's really a joke.
A simple solution hinted upon:
If the ferts are costing more, then using the ADA AS might be better.
Use about 1/2 EI dosing. Works pretty well unless you run really high lights and have very few fish.
Another hybrid method.
You can also extend the water change frequency EASILY to 2-4 weeks this way also, again, without testing. If you want to stick with full EI and run things as before, this also works.
Since you have some coming from the sediment, some from the water column, you have less demand for nutrients at both locations.
So you can get by with less since cost is possibly an issue, I sort of doubt it is, you just will have to say what the KNO3 is for.
But the trade off is using the ADA As which has macros or making your own DIY mud under the sand etc is cost and hassle.
I've written plenty about that.

Wah, this is worse than I thought.
Simple facts I can conclude from the national announcement :
1. You need to have licence in order to import/deal/handle/posses/keep/sale explosives precursor (KNO3).
2. You need to have licence to buy/posses/keep/use KNO3 and only from someone with licence (in other word, it will be sold to you by the right person only if you have licence).
3. Licence is available at cost and trough procedures to be fulfilled, and each licence cost applicable for each certain permit pleaded.
4. Quite a number of rules are to be met before one is considered worth of holding a licence.
5. Exclusions available for certain material that meets certain criteria (KNO3 preparations is limited as 5% solution or 5% w/w). This means KNO3 will still be available to non-licence people as liquified fertiliser or as a mixture of fertiliser preparation.
This licence and control act is sure tough to Aquarists who only use several grams of KNO3 over a course of a month
So it is indeed NOT BANNED at all, just suddenly gone as luxury, dangerous item (just as worse to most aquarist though).
Means we are reduced to buying expensive liquid ferts? Lucky I got a bottle of KNO3 last month. Hope it last me....years...

Still dare to declare that you have KNO3...

I go dilute in water to 5%! .....Think about 200 liters of 5% solutions....that is...a lot of bottles...

hai... nothing to say probably will see increase in liquid ferts price soon
Hilarious!...dilute in water to 5%! .....Think about 200 liters of 5% solutions....that is...a lot of bottles...
But remember that this rule applies from before last month and should some cop read this.... you know the drill
However I'm affraid that it is likely Singapore aquarist will be left to buying liquified fertiliser or perhaps dry form which has 5% or less KNO3 in it.
Over expensive? not necessarily.
I'd be helping Singapore to ease up a bit.
solution can turn bad? I though it is just water and KNO3, unless there is algae or some backteria that turn it into something else
