If you believe Red Sea the G3 series has fixed the past issues with catastrophic seam failures. But they told a lot of people the flimsy seam protectors were enough to keep their tanks seam from failing which happened to alot of those same people. IMO their word means nothing.
I had many of their products (including a G1 Reefer which I fortunately replaced with a tank of a different brand before it failed). There is not a single product I would recommend (the salt may be okay, but I don't trust them not to cheap out on the ingredients so I switched salt as well). ReefWaves getting stuck all the time or breaking, AC/DC adapters of ReefLEDs failing frequently, starting to smoke and (fortunately) tripping my GFCI before starting a fire. The skimmer overskimming even though the sensors are cleaned and/or freshly calibrated and the threshold very low. Detritus accumulating on the "neck cleaner" which just makes it fall back into the tank again.
