Blacknifes 50g Battle of SPS learning

[blacknife]

Half debating just relocating my whole tank here since asking the landlord went so smoothly... would want to either rebuild my sump or get a smaller sump and new return pump.. kind of want to go internal so if there ever is any plumbing problems it spills back into the sump.

Or stick to my first idea.. something small and simple.. Cube coral tank.. perhaps a few fish..

cube would probably be a in kitchen project.. any other shape,size would be bedroom.. headboard reef perhaps?
