My nitrates have dropped down below 10 for the first time in probably a year. I started dosing neonitro again recently to get them back up. Things seem to be happier when the nitrates are between 15 and 20 ppm. My goniopora in particular hate it with the nitrates this low. My Montipora digitata looks lame also. All the other corals, lobos, trachy's, chalices, favia, duncans, plating Montipora, encrusting Montipora, capitata, Pectinia, acans, cyphastrea, Stylocoeniella, turbinaria, symphyllia, Pocillopora, zoas and Ricordia don't seem to care either way. At the same time my Acros have shown no improvement at all, in PE or coloration. Low nitrates in my reef is no bueno FWIW
