Hi,
I'm just about to mix my own EI but don’t understand something. Because this will be the first I'm going keep everything in separate bottles in the first few months to see what happens.
What I don't understand is the added amount of Phosphate. James and ceg advises the concentration should be around 3ppm/week. In the dosing table I’ve found this:
In 40-60 Gallons (152-227 litres) add 1/8 tsp KH2PO4 3x a week.
It's 0.375 tsp/week. By using James dosing calc the result I get is 9.6ppm for a 180L tank.
152L - 11.37ppm
227L - 7.61ppm.
That’s way over the recommended concentration. Please correct me if I’m wrong or missed something. I can’t really see the point of the 3x overdosing. But! I’ve seen on this forum a few days ago some1 accidentally put a tsp in the tank instead of 1/6th and the result was rapid growth. Does this mean the concentration should be even higher than the table says?
And also would like to ask can I mix the salts with de-ionized water? I have about 5 litres from Halfords, it's called "Battery top-up water". Found it in the shed and want to use it but not sure if it’s safe!
I've seen on James site he recommends Hydrochloric Acid for the trace element mix. Do I really need it? What is that for and where can I get some?
Planning to dose everything 6x a week instead of 3 (halving the amounts). I know myself I can get confused easily and don’t want to mix up the days! Can this cause any problems? Meaning the phosphor-iron relationship? Or it’s not an issue once they’re in the water?
