Thanks for the compliment.
main Tank and stand-250lbs.
water in main tank- 125x8.34=1,042.5 (and thats just for R.O. water)
live rock and sand 95+180=275
lights= 100 lbs.
2 mag 12 pumps=15 lbs.
2 -29 gal. sumps; say less rock rubble and some water =250 lbs.
Just a quick estimate just 6-7 lbs. shy of 2,000 lbs.
That is why I put floor supports under there every 3-4 feet, added more stringers between the floor joists, 1/2" plywood, 1/2" cement board and then the 18"ceramic tile.
NO tiles cracked.
