I have to disagree. That person must not have been privy to the type of silicon being used.
My reefer 170
There are other manufacturers using a floating front panel without any where near the number if reported failures. This is my water box 330.7 gallon 84x30x25" tank. My smaller IM20 also used a floating front panel design.
OP IME algae loves RS silicone.
My G2 reefer 300.
From what I've read if a tank like this is out of warranty RS advises to empty it. If it's under warranty it's nothing to worry about.
The seam leaks are cause by failure of the silicone. If RS took the time to dissect a failed tank they would see that. TMK they've never asked to have a failed tank returned to analyze it. But then again maybe they do know and they changed the silicone and added a Eurobrace to take the credit as the fix. We'll never know because they aren't going to publicly state the silicone is the cause. We'll know if the G3s correct the issue in a few years buy they'll never disclose the actual cause. JMO
