I'm not going to debate on whether redsea used substandard glass for the front panel or any of that. I want to focus on one thing, THE WARRANTY
RedSea bills itself as a "premium" brand, but the warranty is TRASH. Three years is all you get from "premium" brands?
When researching tanks for the 6ft peninsula I wanted I could have gone with pretty much whatever I wanted. RedSea, Waterbox, Cade, ect were all options on the table. I actually ended up going with... Aqueon. Aqueon offers a LIFETIME warranty on their large tanks, and that tipped the scale in their favor. It needed to be on a "aquarium appropriate stand", so I contacted them with the plans for a diy stand with 2x4, got approval before even buying the tank. It was super simple to get approval for this.
For a "premium" brand, I just don't see the value in RedSea tanks, simply because of the lack of warranty. Anyone setting up a large tank knows it's a multi year investment to get it going and to a spot where you can enjoy the tank.
