Fertilizer...

I am trying to fertilize my tank,
i dont know how but will try..
a lot to study,
tons to read!!

but what i know would be..
Plant need two forms of nutrient:
Macronutrient :
Nitrogen (N)
Phosphorus (P)
Kalium / Phosphate (K)

Micronutrient :
Cu .. Mg... Fe... Ca... and a lot more..
(Will put in the detail after)

Lets talk about Macro first:
this NPK can be supply with 2 chemical
available in the market.
KNO3 for the K and N
KH2PO4 for the P and K

but the problem is... those chemical is not cheap!!
so!!

Question for me to study...
will spritzer mineral water be one of the provider for K?

humm hummmm...

New Recipe:
1 tea spoon of Mauri-Pan Yeast
1/4 tea spoon of Sodium biCarbonate
200ml of sugar dilluted in...
1.5litre of water
this is the minimum ammount of Yeast i've ever
tried. The whole pack of yeast was 11gm,
i think this time is a quater of the whole pack..
or maybe even less.
Mix the yeast and sodium bicarbonate dry.
Put into the 1.5litre bottle with sugar water in it,
Shake vigorously and walla..
eh?
no foam forming.
Not even the usual brownish color foam.
the color of the solution looks like its still see through.
(Not like the usual one i use to do,
foam building up in a matter of minutes
and the solution color looks somewhat
like 'teh-tarik')
