As has been pointed out limestone is fine. Most limestone's are just Calcite
rather than
Aragonite ( corals , shells etc...), although at one time it was Aragonite, that
has just
been altered during fossilization and is devoid or Strontium. The only real
issue with
limestone, in a reef tanks, is when it is used in a reactor, as some grades are
high in
phosphate. There may be a slight initial rise in the pH. This won't last long as
and sand
or base will get coated with bacteria/organics and will have no effect on pH,
unless
_maybe_ the pH falls below its "pH floor", which is highly unlikely.

Would you consider using 2" or 3" diameter PVC pieces as small pillars?
You cut them so they are just tall enough to stay hidden in your sand
bed, and place them strategically so that your LR is fully supported at
various points by these hidden pillars.
The weight is distributed over the PVC pillars.
If you fear the bottom of the tank isn't strong enough, put a plywood
sheet on the top of your stand, and add a sheet of 3/4" rigid foam.
Place the tank on that and the base will be fully supported.
