Anybody know what the V30 fertiliser contains?It only says"Complete fertiliser" on the label....And can you dose it along with some Fe+ traces?(different days of course)
According to this link it's basically a trace mix with a little potassium.
1% K2O water-soluble potassium oxide.
0.3018% MgO magnesium oxide;
0.021% B boron;
0.006% Cu copper;
0.306% Fe iron;
0.122% Mn manganese;
0.012% Mo molybdenum;
0.006% Zn zinc;
0.002% Co cobalt;
0.002% Ni nickel;
0.003% Li lithium;
0.002% Al aluminium;
Thank you for the link.
I currently use the JBL FErropol with:
0.168% MgO water-soluble
0.024 % Mn
The JBL seems to be higher in Fe ,and lower in MgO.The dosage which they recommend on the cap is 10ml for 80 liters ,while the Dennerle recommends 3ml for 100 liters ,yet it seems to be no big differences between them....
Either way ,I still have to dose N and P...
Thanks ,Zorfox ,I never thought I'd become so interested in math ,when I poured water in my tank for the first time.Manufacturer doses are based on what they think you should be using. It's like someone saying use this much phosphours for PPS versus EI. It's a preference. I like EI, it just makes sense. In fact, why would anyone want to limit nutrients? Makes no sense to me. However, that's MY preference.
I'm working on a new Windows based nutrient calculator. The dry portion is basically done. I'm working on the commercial solutions portion now. I'm thinking rather than limit users to what solutions I have, let them add new ones like the ones you listed. It's all about the percentages and density anyway so why not. Math is math. The calculations are the same for Seachem or Tropica. The only difference being the percentages of nutrients.
You can do the math yourself now right? lol Decide what level YOU want to use and calculate a dose.
btw, if you want to account for the density issues add that to your formula.
what you have now...
Desired ppm / percentage * 10 = ml/liter
Just add the density which is the weight divided by the volume
example Flourish Iron is
Thats a density of 1.05 (2.1 / 2 = 1.05)
0.5 ppm (Desired ppm) / (1% (percentage) * 1.05 (density)) * 10 = 0.4762 ml/liters
Remember. Do the multiplication first :icon_wink
Versus 0.5ml/liter when you don't use density. Not much of a difference. I just hate inaccuracy lol. Besides, if your crazy enough to dose a 250 gallon tank with commercial fertilizer it makes a difference.
