Hi alzak
This is the recipe Tobi gives :arrow: http://ukaps.org/forum/viewtopic.php?f=11&t=14594
Fertilizer Set 1.
For one liter of fertilizer add
25.9 g potassium nitrate
29.5 g calcium nitrate
17.6 g magnesium nitrate
5 g urea Reduce this to 1 gram if you have livestock.
add to 850ml of water then top up to 1000ml.
Dose 5ml.

You would need to add Potassium Phosphate separately....if needed.
1.4 grams of dry powder 3x week.


Fertilizer Set 2.
Here is the recipe for the other salts
74g MgSo4
31g Kno3
12g Kh2po4
Mix into 850ml of water then top up to 1000ml.
Dose 125ml.

You dont need to dose both sets of Fertilizers just one and Trace elements.

Hi
How much are you dosing?
hoggie

 

[alzak]

50ml every other day

 

[G H Nelson]

50ml every other day

Should be 125ml and 60ml Trace.

If you switch to Tobis recipe.
This would be dosed at 1ml per 50 litres tank water.
As you have 250 litres approx you would dose 5ml.

I ml per 50l of Toby's ferts will only give 1 ppm nitrate so you may need to increase

I'm not too sure if that's correct....maybe Ceg can help us out....on those calculations.
Saying that if you do regular water changes ....and have reasonable fish and plant stocking i don't think our tanks will be short of Kno3.
Tap water may have 1 ppm to 50ppm Kno3.

Im not too sure what Ceg was meaning here
:arrow: So adding 5 grams of urea is almost like adding 20 grams of KNO3.?
