Nutrient help

[Ross]

Anyone ever keep damsels in a group. I am running a 65g with 7 fish, absolutely cannot get nitrates and phosphates above 0 without dosing KNO3. My sps are starved. I am debating running full zeovit or trying to add a bunch of damsels to get my nutrients to the right level. I have dosed KNO3 for months and it gets my nitrates off 0, but doesn't seem to do much else. I have played around with dosing acro power and it doesn't seem to do anything at all.

ALK stays low 7s
Cal stays high 300-low 400s
Mag 1240
nitrates and phosphates stay 0.

All salifert and hanna test kits. Tank has been running for about 3 years.

Have you ever tried Oyster feast? I've been dosing a teaspoon(sometimes 2) almost every night in my 60 cube and it's helped me get my phosphates up a little and coral color is looking better everyday. I also get a huge feeding response from sps. Some send out those crazy looking, long, feeding tentacles
