My tank was replaced on warranty for a leak after 6 months. I had also contacted Red Sea via messenger on Facebook when the leak happen, that guy was overseas somewhere I'm assuming due to how the timing on responses played out. But if you feel the US rep is not handling things up to par, I'd reach beyond the US office if you haven't already.
I can say, if this is representative of the silicone they consider acceptable my next tank won't be a Red Sea Reefer.
Lol take a look at my thread they definitely don’t care unless you have water all over your house then would only replace the aquarium itself (not the damage it has done to your house) redsea makes good products but im shocked the way they lowered the quality of the tanks and don’t care that you spent good money for it
