I would do some research on Red Sea gen 2 tanks. They have a history of leakers. I would want to know if this one was included in that history.

I see a great equipment list. Risk of leak is the issue. Ask to see the tank filled, even with freshwater if empty and looks at all seals, for signs of bowing and signs of salt creep

Tank is up and running currently, it has been running for the last 2 years. Going today to give it a good look over. I know the seam issue has been present with Red Sea, and that’s what makes me worry.
 
A better question might be...is the associated equipment, rock and livestock worth the $1000 to you? In which case I would consider buying a new tank, using all the stuff that comes with the G2 it, and getting rid of the G2. (Might make the actual transfer a bit easier as well.)
 
I doubt the nano tanks have seam issues? i have the nano xl g2 and its been running for awhile, i just always assumed it was the bigger tanks that had issues.. Don't think i've seen a redsea nano with seam problems? But thats just me
 
Pass
My first RS tank G1 reefer 170

Oh man….i can’t believe they haven’t addressed such a major flaw….im sorry to see that!

That’s what I have seen the bigger issues with is the larger tanks. Seems like the nanos have had better luck.

Ya you freaked me out so I had to go check my seams lol but they're all good..

Being a Gen 2 , you may get lucky. Gen 1 was the real problem child

This is the seam on my 170. RS has their doubts as well and why it hasn't been addressed lol. They're in denial and reuse to admit the silicone fails and it has nothing to do with the stand or tank sizes tho obviously large tanks put more pressure on the seams.
