Great site BTW Bob.
Add K2SO4 instead. 5$ will get you a lifetime supply. Potash of sulfur by
Green All for 10 lbs.
1/4 teaspoon adds 5ppm to 35 gallons of water or something close. Extra SO4
doesn't cause any issues like NO3 

This way you can add whatever mix of Trace elements while having more
control of those macro nutrients, N,K, and P and not have to worry about
which trace fertilizer you use so much.
Sounds like the stuff is quite expensive your using! TMG in 5 liter bulk is
very cheap BTW and damn good and a proven performer. Adding these, TMG,
K2SO4, KNO3 and perhaps some PO4 is all I think one needs for the water
column. I've used Flourish liquid and their iron but I like TMG personally
but there's not an huge difference.
