Hey everyone, just another newbie here

. Currently im setting up a 44 gallon saltwater aquarium. Ive had a 55 gallon and a 125 before but its just been fish only not a reef setup (which i plan to do this time around). I have a quick question for you. This time around i used live sand (last time i used crushed coral) and I dumped in the sand last Thursday and my water has been extremely cloudy every since. I can't get a clear answer on what i should do. Should i leave my filter running and try to get all the little particles out or should i turn it off and let gravity take its course haha. If you say turn it off, as soon as i turn my filter back on and power head on won't it get extremely murky again? Just as an fyi No, i didn't wash the sand as that would've killed the bacteria growing in it, im using a cheap hang on filter until my new filter comes, which is in the mail. Im using regular tap water with instant ocean salt. On initial setup I mixed salt and water directly in tank, but my
wc i will be doing it separately as well as buying water from my
lfs. Any help would be greatly appreciated, btw everyone in here keep up the good work in helping each other with there problems and questions. Its what made me decide to join because of the community here.
