Those of us (MOST of us) who don't use a "filter" under the tank use a small tank (10-15g in your case) in the stand to hold macro algae (caulerpa, chaeto, rock, etc).
The second you put rock, salt and water together in one place, you're getting crazy. You NEED algae free water or you're going to be VERY unhappy with the results. Sure, go ahead and start the tank with tap water. Sooner or later you'll be fighting algae like crazy and wondering where it came from!
Trop sells RO water, you can get distilled from Walmart, which would be better than tap.
So... if we were back in algebra with word problems and the question was How many 5g containers would it take to fill a 30g tank... what would your answer be?
If you don't slow down you're going to kill a lot of fish, grow a lot of algae and waste a LOT of money. None of that is any fun.
