Been dosing potassium nitrate for a few months to test effect on sps colors. Tried to maintain no3 at 5 ppm. First the corals colored up nicely, and things looked great all of last month, but last week, I started noticing gradually loss of colors. All parameters tested within range, except for potassium which is 460 ppm (salifert). It measured 380 ppm before I started dosing KNO3
Would high levels of potassium cause sps browning? Any known or theorized adverse effects at this level?
Thanks for your advice.
Parameters are:
Salinity 35 ppt, temp 79 f, Alk 9.3, ca 450 ppm, mg 1300 ppm, no3 5 ppm, p04 < 0.01 ppm
