I'd recommend one of those seachem alert badges. I've never used one, but every thread like this, there's a robust conversation about the API test's validity for .25 or below ammonia.
It's also very important to nail down what you mean by "live rock."
If it was wet rock you bought from the store, kept wet, and put in your tank. That's pretty much game-over. You win. People put 3 and 4 fish in quarantine tanks with 2-5 pounds of cycled media. You have 100 lbs.
The problem is that it's become a habit to call any rock that's going into any aquarium "live rock." People call dry rock that was mined by excavators and shipped in a box "live" half the time. If it was clean looking dry rock, then you're in the scenario some people are talking about where it's a good thing you have hardy fish that can withstand a little ammonia. Chances are the worst has passed, and your tank is well on its way to being cycled. You still want to keep an eye on it though and go slower with adding any more fish.
Third option is a real longshot. Apparently it used to be pretty common to order dozens to hundreds of pounds of ocean live rock. It was shipped damp. A lot of the life on it would die. Putting it in your tank would pretty much mean it was cycled, but so much of the stuff on the rocks would die off and cause an ammonia spike.
Maybe some FOWLR peeps will chime in. Less stringent testing requirements than for a reef to be sure.
Great looking tank!
