I have an established reef about 4 years old. Primarily SPS; about 2 months ago I had a nitrate spike of about 60 after I used Vibrant to get rid of some hair algae in tough spots (it killed algae within my two week dose of 30ml once per week). I typically run the tank anywhere from 5-10.
Nothing has really changed; I never did major water changes in the past. My livestock is fairly low for a 300G tank. 96x30x24
Livestock: 3 yellow tank, 1 sailfin tang, 1 blue tang, 1 powder blue, 2 clown, 1 anthias, 1 diamond goby, 1 green wrasse, 1 melanaurus. (No fish death in the last 2 years, ammonia is 0/nitrites are 0)
Skimmer: Lifereef oversized 36 inch rated for 400-600
Salt: instant ocean with 5 stage RODI. Water tests 0 no3.
P04: 0.05 according to hanna ULR and 0 according to salifert (junk/useless)
I have tried vinegar dosing, currently been using 50ml of nopx every day for the last month and it has done NOTHING. At this point I am so desperate I don't care if I wipe my tank and tried using AZ-NO3 and nothing. I am also dosing 50ml of microbacter7 daily. Chaeto in my algae reactor is not growing at all and starting to die.
I have always vacuumed my sand bed daily; it's only 1.5 inches at best and I have tons of rock in the tank.
Over the last two weeks I have changed out over 500G of water doing 50-100G a day and nitrates are still 50+. Has my tank reached the age where it's just destined to die? I am tooth grind mad right now over this crap.
