I think it won't be a good substrate for plant growth
there will definitely be sharp edges your fish could hurt themselves on
and it will take you a LOT of work to achieve the size of grain you'd be shooting for
sorry to be a nay sayer- it just sounds like an ungodly amount of work for something that won't benefit you at all.
i'm always looking for cheaper options too- have you looking into the aquatic soil people on this forum have tried from home depot and lowes?
