Welcome to TRT! Congrats on a cool tank I love mine (most of the time) The ceramic rings and
bio balls will collect nitrates and drive the levels up to high for a reef.
I don't use a heater on mine so I'm not sure about the power cord issue.
Some people have made a little "fuge" in the 2nd compartment or just add live
rock rubble to help with filtration. My 2nd compartment had a sponge in there so I would remove that if you are going to add rubble or a fuge.
Plan on weekly 2-3 gallon water changes or 5 gals bi-weekly with your live rock will be all you need!
Keep us posted on your progress
