KNO3 and KH2PO4

**samuelgoh** · 3rd Feb 2006, 16:26

Hi guys, i just bought the above from NA in solid forms.

1) How do i go about calculating how much i need for my planted tanks ?

2) Do i dose them dry or mix with water then dose ?

My tank is about 127 L / 30 Gallons.

Thanks

You can either premix it with a certain amount of water and then dose by ml liquid form... Or just agar agar dose in solid amount (based on Chuck's calculated values) into the tank...

Note that Chuck's reccomended amount for NO3 is way too low... I'd go at least double the amount (10ppm if I'm not wrong)

can anyone confirm ?
cos if that case, i need to aim more KNO3 to my mixture liao.

anyway, for the small spoon that comes with the LUSHgro, is it equals to a teaspoon or tablespoon?

The big one is tablespoon and the small side is teaspoon i supposed...

Look at the markings on the plastic thing. The 5ml one is teaspoon. 15ml is tablespoon.

Tom Barr's EI gives a range of 5 to 30ppm. I aim for mid-range.

Yes, for KNO3, which refers to mostly nitrate

valice, guess u say wrongly....5ml is teaspoon and the other 2.5ml is 1/2teaspoon.......

so for convenience sake, i always use the small side (2.5ml) since i'm suppose to does 1/2 tsp of KNO3 to my tank twice a week....it'll be more accurate..

Err... Isn't that what I said? Small side is teaspoon and big side tablespoon?
I can't remember what is the ml values for the two though...

think he meant that the small size is 1/2 teaspoon and big size is 1 teaspoon.

anyway usually the KNO3 , you guys will used a lot more as compared to the KH2SO4 right ? as in accordance to the recommended ppm

persoanlly i like the high side..my kno3 for my high light tank is running at 30-40ppm for the entire week
as for Po4.. i dose 1-1.5ppm every 2 days..

OH! Issit?

But the big side is so big? The spoon you have is the normal one which the doctors will give when we eat medicine right?

So the big side should be 1 tablespoon instead of teaspoon...

Isn't this what we should be doing if we going EI?
That's why need to diligently change 50% of the water weekly...

*Although I haben done mine last week...
