I’m currently in the process of deciding on how to upgrade my 8 year old 40B reef. I’m stuck between a planet 120 (48 x 24 x 24) and their 150 (60 x 24 x 24). Also trying to decide if I want to do an internal or external overflow. I have settled on a peninsula configuration.... pretty sure. I plan on a DIY stand, canopy, and 40B sump. I just can’t decide if that extra 12 inches and ~30 gallons is worth it?? I do have a really nice show piece leather either way . Equipment wise I’ll be looking at all new powerheads ( bye mp10s) and skimmer ( reef octo 110). But I will be able to use my gen 3 and gen 4 radions and my apex. I plan on keeping predominantly lps and softies but will venture into some Montis perhaps. Thanks for your time, I want to take my time now planning the tank as this will be my last one for a long time

Peninsula tanks are great but they do require a proper layout to look cool.
