Hey there! Welcome to SD. I am a nurse as well, working in a cardiac ICU...it has been a trying, long season for sure. Glad you found solace in the ambience of your new aquarium...very nice of your hubby to bless you like that...it looks very serene and a great place to destress & unwind.
With your regular maintenance plz be sure to clean the debris from amongst your rock work as it can become the source of high bacterial counts that will diminish your discus health.
All the best mate
