I think somewhere along the way ULNS got a bad rep, but I don't necessarily think they're bad, just often not implemented well. The idea behind it is not low nutrient from low feeding but from massive nutrient export. This takes years and a very mature reef to pull off successfully. In your case I would likely start dosing nitrites and reduce the phosphate export until they are at least measurable.

This is my tank before I moved. ULNS. No measurable nitrates or phosphates and I fed this tank like this 2-3 times a day, essentially a small flat of hikari mysis per day, nori, and 5-7 cubes of frozen. Best watched 1080p and fullscreen.
