I need some help . Serious help. My current system is totaling in 60 gln water roughly excluding rocks and ext . I am using 17lbs on live rock and two large marine pure bricks in the sump , Large alpha 170 protein skimmer for nutrient export . Ati 8bulb hybrid power module and 2x 6095 tunzes flow . I have multiple frags of Sps over 40 frags and variety of Lps and 4 fishes that's are heavily fed sometimes 5 times a day more than 2 or 3 cube that I was feeding my 220 gln last years . Tank parameters are as follows
Ph 8
Alk 9.5
Cal over 400
Mag 1300
Phosphate 0
Nitrate 0
Temp 77
Salinity 34

I cannot get any readable nitrates no mater what I do . Now I haven't change water since last month it's been more than 40 days and with list of corals and fish feeding including amino acids my phosphates and nitrates are still 0 . Corals are growing very slow and dull in color all alive thou . Lights are running for 12 hrs a day 8hrs on its peak .

try bringing your alk down around 7, very low nutrient systems do better with lower alk closer to sea alk level. maybe get more fish to produce more coral food.
 
Lights come on at 7am slowly ramp up to 70% and shuts down at 6pm. LEDs at 40% max. Through out photoperiod only 6 hours when 8 bulbs are lit together .
 
No algae what so ever. I clean glass every week and now since I been feeding more probably every 3 to 4 day I have to clean the front glass
