I bought sand the other day and i rinsed it till it was pretty clean. I guess PRETTY clean is the key word, but anyways. I put in the sand and it was very cloudy/murky. I woke up this morning after it was 8 hours since i have put it in, and still saw that it was cloudy. I put in some accu-clear to help it become less cloudy, but it still hasn't helped. How long will it take for the sand to settle? I have also changed 1/3 of the water since it was cloudy. PLEASE HELP!
