120g switch

So we are on the final countdown here ready for the big switch. 120 in place. 55g sump in the basement. Plumbing should be done tomorrrow. Almost have enough RO water to fill the 120, hopefully can check for leaks in plumbing tomorrow. Return pump=Reeflo Tarpon. A ginormous skimmer (Warner Marine), Typhoon 3 RO set to be delivered Tuesday, meanwhile our house Culligan RO is doing a great job, Rubbermaid containers need to be bought for Ro & mixed SW. Anything else we need to be thinking about? This is not a completely new setup, we are combining our 54 & 75 reef tanks into one. Will use existing heaters, GFO reactors, auto top-offs, & of course have plenty of LR to transfer. Anything we're not thinking of??  Lighting is covered also. yeah and hubby says no pics til he cleans thing up a bit... but then .....

 

Sounds like a great setup!
I would test plumbing with tap water so you don't waist salt if you have leaks or other issues.
