Mixing Flourish Trace and Iron for dosing pump
I have decided to acquire a 3 pump dosing pump to automate my fertilization. I am dosing Potassium Nitrate, Monopotassium Phosphate and trace (including GH booster w/ every water change) using the EI method with a tweaked Nitrate dose. I want to introduce iron using Flourish Iron. I was wondering if I can mix the flourish trace and iron together using 1:1 ratio to replace my trace dosing. I only have 3 pumps and I want to avoid buying another dosing pump just to dose iron. With the 1:1 ratio I will end up dosing 6 ml of the trace and iron mixture.
I wanted to know if anyone has done this before. Again my goal is to simplify the fertilization process hence the use of the dosing pump but unfortunately I only have 3 pumps and an additional pump will probably cost me another $100+ so I wanted to know if I can save money by just mixing iron and trace.
