Waiting on DT...What to add to my live rock tank while I wait.

[David3147]

I have about 30 lbs of KP ocean live rock sitting in a 20g long waiting for my DT to arrive in about a month. It's starting to grow a little algae so gonna add a mini CUC. Other than that was thinking maybe it's time to add a juvenile tang bought from QT source. Good idea or bad? (Prob a tank raised 1-2" juvenile yellow tang). All fish are coming from trusted QT / medicated source.

DT is a waterbox 190.5 (about 140 gallons)

I say bad. Stick with the CUC for now.
Tangs can be little stress babies. Putting them in a new tank, then a month later into another new tank is too much IMO.
Again, just how I'd do it. Your experience may vary.
