I guess that means I shouldn't use the sal****er from the ocean either
huh?

Some consider sw from the ocean to be the best. You have to be very
carefull where you get the water from though. As an added bonus fresh
sw often contains plankton and whatnot to feed your corals. There have
been related posts to this group in the past. search

Sand is different. I have not seen any body recommend beach sand.
