upthrust keeps the object floating
the gravitational pull keeps it along the meniscus of the averaged water
You say that the two forces are in equilibrium.
Isostasy is a state of gravitational equilibrium where the weight of the Earth's crust is balanced by the buoyancy of the mantle below. This equilibrium is achieved when the crust floats on the denser mantle and remains in equilibrium at a certain level.
If the net force is zero, then the forces are balanced. If the net force is not zero, then the forces are not balanced. You can have a balanced pair of forces, but not a pair of balanced forces.
If the forces are balanced, then by definition the sum of the forces is zero.
Balanced forces do not alter the motion of objects.
Balanced
You say that the two forces are in equilibrium.
During the time, you're pushing it, the forces are unbalanced. Once you stop, they are balanced. Unbalanced forces result in a change in motion, even if it is slowing it to a stop. Balanced forces produce no change.
something
While you're moving, the forces acting on you are unbalanced, and add up to something. When you're sitting, the forces acting on you are balanced, and add up to zero.

If the net force is zero, then the forces are balanced. If the net force is not zero, then the forces are not balanced. You can have a balanced pair of forces, but not a pair of balanced forces.
Unbalanced forces is when the forces are 0N or more. Balanced forces are 0.
If the forces are balanced, then by definition the sum of the forces is zero.

balanced
A balanced group of forces has the same effect as no force at all.
