Upgrading to a 260 Gallon Tank

[Abe K]

Going from a 125 gallon to a 260 Gallon tank. I am trying to use most of the equipment
I currently have:
3 HYDRA 26 Lights
2 MP40 pumps
1 Reef Octopus 220 Skimmer
1 Echo Tech M2 Return pump
1 500W Heater

What do you think I can re-use?

I will be replacing the sump
