I owned a reefer 200 gen 1 … failed after 8 months. The replacement tank is fine. Reefer 425 gen 2 , failed at leak tests lol. So i don’t know if its the design of the seam or the quality control. While I can say the aesthetic of RedSea is beautiful, I question there current quality of production. But they are a mass produce product so it’s understandable a few mishaps will slip through. Rimless will never be as study as rimmed or eurobraced. The horror stories you hear will always be LOUDER than most of the happy clients they have. It’s inevitably that a tank will eventually fail, 5 years or 20 years, have a plan for when that happens. I have had many RedSea in the past, even with the hiccups, I still would recommend them overall.
