Let me just say the API nitrate kit is junk! A while back I kept dosing nitrates because this kit kept saying 0ppm. I couldn’t figure it out. Then I ordered a Nyos nitrate kit. Highly recommended!!! And my nitrates were in fact much higher than 0ppm. More like 12 ppm. The Nyos kit is easy to use and is pretty dang accurate! Especially in the lower ranges. I’d recommend this kit to anyone. And definitely pick up the Hanna ULR phosphorus Checker. “HI736” ... I don’t run GFO, filter socks, etc. I keep my nitrates at about 5ppm with phosphates at .07-.12 With the accuracy range of the checker I don’t push .03.... Too close to zero. I keep mostly LPS and softies. I noticed my hammers and torches not expanding several months ago. The Problem was nutrient availability. Tested 0 nitrates and 0 phosphates. After bringing these levels up within range everything made a 100% improvement. Polyp extension and colors slowly got better after several weeks of dosing and everything is back to “normal”... I still have to dose for phosphate regularly, but not as much for nitrogen. I will never run a system with these levels at or near 0ppm again. We all know what can rear it’s ugly head when nutrients bottom out. Yup, dreaded dinos.:mad: But that’s another story. So yes to higher nutrients for this reefer!!!
Your LPS will thank you also!
