Newbie 75 gallon

[Llorgon]

Been awhile, have been on vacation the last few days. I did get my new return pump before going away though. Turns out it was the controller that had gone. Plugged new controller into the old pump and everything is working fine.

Good news 2 of the smallest acro frags are getting some colour back!

Unfortunately my acan isn't looking very good and same with my hammer coral.

The frogspawn is doing well though.

Any idea what I should do about the hammer coral and acan?
