EI dosing problems come again
Tank size 190 Liter (50G) 90cm X 45cm X 45cm
Light 180 watts (8~10 hours)
Heavy planted
Mixing a weekly dosing solution
Weekly Dosage 30ml of the pre-mixed solution. (10ml X 3 a week)
Prepare pre-mixed solution in 250ml tap water:
Ingrident
KNO3 10tsp dry then the NO3 15.83ppm
KH2PO4 0.5tsp dry then the PO4 1.20 ppm
K2SO4 0 tsp dry then the SO4 0ppm
after that the K is 10.614422ppm from KNO3 and KH2PO4
This was all achieved using one of those excel based EI fertilizer calculations.
Does it seem correct? This would be a 2 month (8 week) stock solution.
If my take is 50G so approx 190 L (166 L if conisder substrate, rocks, plants, wood, etc) then my ranges should be:
CO2 range 20-30 ppm
NO3 range 5-30 ppm (I'm in the mid range at 16ppm)
K+ range 10-30 ppm (I'm in the low at 10.6ppm)
PO4 range 1.0-2.0 ppm (I'm in the mid range at 1.2ppm)
Fe 0.2-0.5ppm or higher (this will come from CSM+B Plantex when arrives as it is high in Fe, now from liquid iron fertilizer)
Should I use more KN03 which would increase the K+ but would also increase the NO3 level? Or just I leave as is?
