Folks here need to realize that maybe not everyone have their planted tank as their top financial priorities; and for some folks, it's a HOBBY and not a life-changing event.
I think he gets it - increased $$ = increased proliferation (better filters, higher WPG, super substrate, Co2, etc...). Although at this point; guy wants simple advice. How about passing plant-specific recommendations on what is acceptable for what he has?
I certainly wasn't suggesting he spend hundreds of dollars, only that the crushed coral isn't ideal, even for many of the nicer beginner plants such as Ludwigia repens and Rotala rotundifolia, both of which are usually staples for beginners and often found easily in stores. My point is to help give him the greatest chance of success.
Any cheap inert gravel would suffice better than crushed coral in my humble opinion.
