I know that I used 80 pounds of sand, but it shows 92 pounds.
Tank material weight says that it is 136 pounds but was told that a 90 gallon is actually 160 pounds dry, so I may have not gotten the glass thickness quite right. I also must have very close to 100 pounds of rock in it as well.
Not sure what the recommended lighting is all about perhaps its for a fish only.
Like it says just an estimate.
