It varies depending on how diligent you have been with your maintenance.
Right now, because of several lengthy business trips, I am working on my
tank almost non stop to correct some nitrate problems. In a normal week, I
wipe the glass once a week and clean the skimmer once a week, dose every
other day and top off water twice a week.

Normally I spend about an hour a week working on the tank. This week its
probably two hours a day due to my nitrate situation.

Tank is a 50G reef.

I am a newbie who wants to start a large sal****er mixed fish/coral
aquarium. How much time per week does it take to maintain a large
aquarium of this type?
