Dude, you have to wait until there is NO ammonia, nitrite, or nitrate to add corals... Your cycle will take WEEKS (I highly doubt another 2 days will stabilize your system), even longer if you are dosing ammonia regularly (dosing ammonia is only to BEGIN a cycle in order to kick start a new tank's ecosystem - you are typically supposed to STOP after dose #1). When your water is clear, you have no ammonia, nitrite or nitrate... ONLY then it might be time to CONSIDER adding livestock. Your canister filter is only going to propagate nitrates... I had one for 8 weeks on my current tank, and it could NOT process nitrates even with the super-expensive biomedia.
What size tank do you have? What's your water salinity/specific gravity? PH? Alkalinity? Nitrite/nitrate readings? Phosphates? Copper? Tap water or RODI? Salt mix? Livestock? Powerheads? lbs of Liverock?
You should have initiated the cycle with uncured liverock, salt water with a 1.023-1.026 specific gravity, ~8.3 PH, appropriate alkalinity, and NOTHING in the tank. Let the tank do it's nasty (it took mine 6-weeks) and once it stabilizes, CONSIDER putting in a clean-up crew. Wait another week or two for readings to stabilize and then CONSIDER adding non-coral as desired... once your desired bio load can be compensated for by the ecosystem, and Nitrates are at 0-20 you can CONSIDER putting in SPS/LPS corals. Realize that every change to the ecosystem is going to change the bio-load and could, potentially, initiate another "mini-cycle" - I plumbed in my sump about 2-weeks ago, which added 20lbs pre-cured liverock and 10 lbs live sand to support the display due to my nitrates being 40-60 - I ran the sump on it's own filtration for 2-weeks before that waiting for a cycle (yes, pre-cured liverock may still need to cycle if removed from water to transport). When readings were solid and there was no die-off (ammonia/nitrite), I did a trickle plumbing feed (partial water from tank to sump, and vice versa at much less than <1 gph) to merge my sump and my display tank in order to reduce environmental impact. My hitchhiker corals (they appear to be pagodas) now seem extremely happy and they were rather weather-beaten with my nitrates >30. I'll be giving it a minimum of 2 more weeks on the sump and evaluate the water chemistry before I add anything else...
Moral of that story is don't be impatient. It takes more than ammonia and 2-weeks to establish a 5-300gal self-supporting boxed-up version of the ocean...
