No where in this thread have I seen mention of the tank's temperature or heater(s).
What is the current tank temp? How stable is the temp during a 24 hour period?
Do you have a glass top or other solid cover on your tank?
You have a 125 gallon tank with 60 pounds of LR
. The recommended amount of LR
is 1˝ - 2 pounds per gallon. I have 180+ pounds of LR
in my 125 tank.
You added a clean up crew for a 125 all in one shot. A clean up crew needs to be built up slowly as you increase the bioload in the tank.
You have attempted to instant cycle the tank, which has never worked to my knowledge. It's not your fault, you were just taking the advice of your lfs

You really should step back now and look to start your tank properly.
Take the remaining livestock back to the lfs
and tell them they need to hold it for you or refund your money for now.

Step back, start over, go slow, and you will end up a succesful show piece aquarium.
