Help! Did I kill my Toadstool?

[TheReefGeek]

You registered ammonia when you added a few fish into 150g total water volume?

Couple things that might help:

1. You say 100+lbs of live rock, I would have 150lbs min. in your setup.
2. Your seaclone skimmer is probably not good enough for 150g of water
3. I would swap out your crushed coral substrate for 1" of oolitic aragonite sand, or 3-4" of mixed grades, whatever you like the most.
