I’m totally new to reefing I’m just a little over my head now. I have had a 29gal bio cube for about 5 years. It crashed right before I moved into my new house, which was about 4 years ago. When I moved my wife told me to sell it that some day we will get a bigger tank. Well that time has come we picked up a Red Sea reefer 750 XXL. It’s just so big I really don’t know where to start. Any suggestions would be very helpful
