I totally agree with Dave about the RO water. I tried to use tap when I started and it was a disaster. Spent more time trying to clean glass and rock work then I did enjoying the tank. Try your LFS they should have just RO or already aged salt water. In a pinch Walmart sells ro water (make sure it's a green label "drinking water" the fine print on the side will say RO). As far as the wave maker with Koralias they aren't supposed to be put on one but I've been running them that way for over a year with no problems.
