I've got the 6X3 from pentair and it works great for me some minor paint chipping but my rays haven't minded.

Yeah I think they look pretty good especially in a fish room environment. But Pentair is adding such a high margin. Pentair sells that tank of yours for $886 plus shipping while it’s listed at the supplier for $289 with $150 shipping. Basically half price ! And the savings are even higher on the larger tanks 8x4x3 from Pentair for $2200 plus shipping verses $458 +$150 direct !
