48x18= approx. 6 square feet. How many square feet does a 20 cover ?
I used three 50's in my 125 for approx. 1 1/2 inches to start.
I used the (what I call) bag rule (considering I used 50's).
Lay the bag length wise to the tank. Halve the bag thickness for the increased width of the tank and you will be close I think.
My 125 is the same as your 75 in width/depth/front to back, however you look at it, just 2 feet longer (side to side). I used three 50's and came out pretty good. If you use 20's, I'd say three to start.

has a nice little chart that breaks down lbs sand... just scroll down you will see it.

rule of thumb:
10 lbs of sand per gallon will give you a 1 inch sandbed.
2" inches x 75 gallons = 150 lbs of sand
