I am still troubled by the death of my corals when all chemical parameters seem fine. I ceased dosing NOPOX and have shut down my phosban reactor. I feel I have a large enough fuge with enough Chaeto to keep nitrates and phosphates in check. Perhaps the coral would have prospered with trace amounts. I also noted that I had 40v of stray voltage in tank. Although I believe this has no effect on corals , I installed a stainless steel grounding probe just to try it. Since I stopped dosing and running reactor the pH went from 7.9 to 8.1 almost immediately. I ride this out for a while
