I apologize in advance if this is the wrong place to post this, not sure if it should be in chemistry or beginner, or where. I'm new to this forum (much more active than others)
About a month ago, I started dosing KNO3 and Phosphat-E to balance nutrient levels. I had no detectable NO3 levels and PO4 levels around 0.25ppm according to the Hanna ULR Phosphate https://hannainst.com/phosphate-ultr...-hc-hi774.html
I tried ROWAphos, but because I only had a bag in the sump it wasn't very effective. I subsequently went with the Phosphat-E in an attempt to get the PO4 under 0.1ppm or so. With repeated dosing, I could only get it to about 0.15ppm, though I was able to raise NO3 to around 2ppm. My latest Triton report is listed here https://www.triton-lab.de/en/showroo...icp-oes/74258/ which looks like it is indicating a PO4 of about 0.0070 ppm and high lanthanum. So clearly, to me this means I need to STOP dosing the Phosphat-E now. However, my question is, how should I further monitor phosphate levels? I would assume the Triton is more accurate as the home test has user error...My SPS don't look too hot (and haven't in a while, which is why I started dosing in the beginning) Should I use a PolyFilter to try to reduce the Lanthanum and Lithium?
