    I've recently switched from using Flourish to Rexolin APN for my trace nutrients. I'm having some difficulty calculating how much to use. In Tom's article it states that for aquariums from 40-60 gallon, 1/8 tsp+/- is sufficient. However, when I put that amount into this calculator for my 45 gallon tank it says it will only give me 0.15ppm Fe. This seems to be too low. Please let me know how much I should in fact be dosing. I'm otherwise dosing EI. My tank has pressurized co2 and 2x39w T5 bulbs and measures 36x16x18. It is densely planted with various fast growing stem plants. Thanks in advance.
