I have a 1st gen rsr 350. I am starting to see some water creep into the seam on the right side. I sent pics to Red Sea but the tank is out of factory warranty by 8 months.
They offered me $800 for a whole new tank and stand. I told them I only wanted the display tank and not the stand b.c I will do my own plumbing underneath. They said that is not an available option. Unfortunately, I am not ready to commit $3k to another tank.
Well that sucks..
Sounds like you need to take it down though. Petco sales is going and their tanks are more reliable
