I didn't say it was SO MUCH less expensive, I said it's cheaper usually. The full tank package for that particular Fiji tanks is $1999, but if you look at say the 81G EXT Full tank package it's ~$2300, tank, sump, stand, included the closest Red Sea Offering is 88Gallons for ~$2800... they go back and forth, overall, I think the Fiji's are better buys... but that's a personal preference...I found this - from Fujicube - its $300 different. Is it so much less expensive?
