Looks like you and I have about the same system I'm now at day 12 and apparently completely cycled to my suprise. I think the difference is I started day one (to review) 17 lbs fully cured and wet fiji rock, I only used 10 lbs of live (damp) sand and the premixed store bought water game me a terrific boast. Over the last couple of days I added 3 turbo snails, 3 dwarf hermits a small xeinia frag and a coral banded shrimp Everything minus one hermit is alive and well. I'm trying not to overfeed, and I clean my sponges twice a week (they get funky too) Skimmer is really starting to stabilize and produce, My heater is finally settled in at 77 to 18, Lights are steady on timers and I have to circulators on wave program running 15 seconds each with a 5 second pause between switching. I use 2 slipstream nozzles so my water flow is great. You can't be far form the end of cycle. but again I would suggest cutting out food till you have livestock as I believe you have produced enough fuel for your cycle. I think nitrites will drop at any time like a brick off a building, then 25% water change and you'll be in business, Good luck buddy
