You can put this solution on YOUR website!
The tank is 20" high.
It has 5" of water in it.
Fish add 1 1/2 " to the height of the water.
He leaves 1 1/2 " to spare.
To fill the rest of the height with water it needs to be
20" - (5 +3 1/2 +1 1/2)" = 20 - 10 = 10"
He need to raise the water 10 more inches.
