Question on tank upgrade

[fau8]

Okay, my current equipment is fine for this upgrade, but what changes will I encounter going from a 75 gallon to a 150 gallon?

Your equipment is fine as in what? Sump? HOB equip?

longer maintence times? you sure the equipment is going to be enough for the tank being double the size of the smaller?
