ok lets hit a this one at a time.... pool filter sand - no no
beach sanc - no no
both because they have a ton of silica in themand they will creat a wonderful base for all the algae your tank can fit!!!!!!! LOL no really it is a bad idea....
a sfor sand depth it has been shown that 4+ inches or under 1 inch is best anything in between creates issues...
now for the main idea you can get deas sand and finely crushed coral to mix and then add a little live sand later to add the bacteria to the mix.... it will be cheaper and have great effects.....
