Welcome to AA!!!! This is where the addiction starts..
A 58 GAL
is a great reef starter. The size is good, and costs are lower than most tanks.
Lighting will all depend on what you want to keep. Read all you can regarding coral keeping. Some will thrive with pc
, and others will thrive with MH
I would go with the refugium if you are keeping corals. Wet/dry is nice, but you will want to remove the bio balls and replace them with reef rubble to control the nitrates.
Whatever your lfs
tells, check here to confirm whether it is correct or not. Many times lfs
are only out to sell you things without worrying about the problems you will encounter. Post your questions as you read through. Everyone here is very friendly, and eager to help.
