Hello and thanks for stoping by to see my problem. So i recently made some threads that my euphyllia were feeling really bad and i just could not find the problem. So just to get to the point, about a month ago i bought 3 different types of coral foods and i fed every other day the corals and i blasted them with this food, and by the way i did not have a refugium for stoping nitrate growth. So i kept on feeding them for a month and i saw insted of gaining color they all lost color and to my surprise my montis started to discolorate but my acros were perfectly fine. So i did not pay mich attention because i thought if the acropora was ok than nothing was wrong with my tank. Untill one day i scrubed the tank glass and woke up the other day and it was worse than the other day and the corals were **** to . This continued for a week and i got myself a new nitrate test and it showed over 0.5 to almost 1.0 i quickly build a refugium and did a 40% water change and did the next day another 40%. I know i know i stressed all tank inhabitants but they already suffered to much! So then i checked my nitrates and phosphates but they did not come down a bit!! So please help me to bring down my nitrates!!
