I have been dosing ATI essentials for some time. This is my first dosing experience, so it took me a while to get everything right. Anyway, calcium is steady at 420ish, alk is steady at 8, magnesium is around 1400. The issue is that my magnesium doesn't drop much. I have two magnesium test kits and both show the readings rarely fall, so i rarely dose the #3. I dose 10ml of #3 once a week. In contrast, I dose 104ml of calcium (#2) solution every day. I am thinking that this means I am missing out on a lot of trace elements as you are supposed to dose stuff equally. I have done two ICP tests and in both tests the trace elements were zero or way too low. Magnesium, however, was fine. Now I just do water changes every two weeks to replenish trace elements. I am wondering what ATI would recommend in this situation? I don't want to dose too much #3 and raise my magnesium too high. But I am clearly not getting the trace elements I am supposed to have. I will also note that I am running GFO and carbon, which I recently learned is against the ATI recommendation to have running constantly. I am not sure if that plays a role in trace element depletion. P.S. ATI's ICP web interface is awesome, nice job!
