Wow! Thanks for all the replies!
I did use tap water treated with Prime and I mixed the salt in the tank, since the tank was empty. I read that it was okay as long as you have an empty tank. For future water changes, I have buckets and a water pump and heater to mix it for 24 hrs. I haven't had much evap, because I have kept the tank covered and light off. I did have my specific gravity too high for the fist day or two and then I took some of the SW out and added treated tap until it came down into the "good range". The water has been in the tank with the koralias and heater running since Friday evening, so it should be pretty well mixed and aerated, I hope!
I did rinse the sand, but it still got super cloudy for the first 12 or so hours after putting it in. It kicked up everywhere too at first. It's a lot lighter and finer then the blasting sand I have in my FW tank! I did use a paper towel to sort of wipe off the inside of the glass, which got some of the sand off, but this stuff is white and hard. I didn't want to scrub with the paper towel because I didn't want paper bits coming off into the tank, so I quit. It reminds me a lot of the hard deposit you get from evap at the top of a tank, but it's not at the top, it's in random areas kind of in the middle of the glass, almost in a horizontal linear pattern like evap deposit too, but it's definitely not from evap. I'm hoping my new scrubber will come in tomorrow, but I have a feeling it may require a razor blade or something of that nature. Not sure!
Maybe I should look for a skimmer after all. I don't really have room for a sump at the moment, so it will have to be a HOB skimmer.
I think maybe if I get like 5 to 10 lbs of base rock, that would make it look better. If I ever get the white crud off the glass, maybe I can try to post a picture to see what folks think? lol
Thanks again!
