as my title says, i need help. From one day to another, my take became over 75% covered with i believe to be cyanobacteria. i have a 75G with abit over 120lbs of live rock. Everything started after i stopped dosing vodka and vinegar. My P02 is low, trates are low, i changed bulbs about 2 months ago. My tank looks depressing as it is now. Here are a few shots. I've tried leaving it in the dark for 2 days only turning on when i feed for 20 mins 3 times a day.
