Will these blocks have a better shelf life in left in the sump?

Welcome back.

In two years time, see the blocks yourself.

All good porous media will erode and break down over time.
These blocks however are too brittle and friable (for real life practical use) to my liking.

i dont really get your question... the blocks are meant to be placed in the sump to begin with.
