We prove that if the fundamental group of an orientable finite volumehyperbolic 3-manifold has finite index in the reflection group of aright-angled ideal polyhedra in $\mathbb{H}^3$ then it has a co-final tower offinite sheeted covers with positive rank gradient. The manifolds we provide arealso known to have co-final towers of covers with zero rank gradient.
