Great thread, very nice setup.
I'm 2 years away from a big tank setup. Building an addition, great room + garage. I'll be looking very closely at electric costs for equipment I buy.
I went with Tunze for movement on my current 125g. Nice flow, low energy cost. Your tank is about the size I am looking for.
I may go 8-10' 36" front to back & 28-30" high
Good to see you are still working on the tank
Take some time to enjoy it when you can
