Hello all! This is Norway calling….

I have a question related to dosing TMG. I have 60g tank with 2,35 watts/g. and pressurised co2.. (30ppm) To get 0,5ppm Fe after a 50% WC, I must dump 90ml of the solution into the tank. This is much more than the EI says about dosing traces. I’m afraid I excess some of the other substances which is present in TMG. This gets expensive too so if I keep up feeding the plants this way, I have to cut down on the food for the kids…. :eek:

The question is, should I stick to the EI and use something else for Fe?
