I don’t know what happened but the quality went way downhill. No difference between them and the Red Sea systems anymore, besides the absurd price tag. I essentially wasted $14,000 on a new 200XL. It’s absolutely not any different than my Red Sea system. In fact the glass clarity is probably worse, as are the overflows my (very reputable) LFS confirmed that the quality had dropped off a lot when I asked. Now I try to warn people not to buy new ones. In fact the overflows are so bad I’m scrapping the entire system soon.
