after reading your tread back and forth trying to ex-orb it all in
than I come to this quote you stated .
using new base rock and sand is all good , but after you said you added water from the old tank than added fish I had to stop and scratch my head,
first I must think you carried over trates from the old tank via the water
now looking at it again new rock and sand added water than fish
adding water from a old tank don't make it automatically cycle instantly if at all
I hate to be the bearer of bad news but your tank never cycled
I came to this conclusion from process of elimination from all the above posts
I would take your fish to a pet store to hold for you or if you have a friend local who can hold them for you
after you do that get a nice size deli shrimp put it in a ladys stocking and let it float in the tank till it starts to decompose and you see ammonia of 4 ppm
than you can remove it ,
this will begin the cycle you never did
this article will help you through it step by step many of us here used this to start
