Sounds fine but the next time you may wish to try a total
micronutrient mix which includes several other trace elements.
You'd hate to have lots of iron, but run out of manganese or zinc.
Since it is a low-tech tank (no CO2?) you wont need much.

Keep the solution away from heat and light, but why the fridge?
Half-life is probably about one week in the tank. It depends upon
pH, light, heat, turbulence in the water etc. I have been using
the stuff for three or four years now.
