Yeah- I think I am going to stick with my Seachem Iron- seems to be a good product to me. I don't like the Seachem Flourish (trace) though- it is smelly and dark coloured, and I find it colours my water by the end of the week :/. I want my water to be clear, but instead I keep getting a brown tinge to it and it takes away from the colouring of my plants.
Anyone have any sort of idea of how I should go about making my own GH booster from the three minerals listed?
