Which type of quikrete did you use? It's possible you used a different type than I did? But as the pictures showed, even after we rinse the sand off in buckets, it was still ridiculously dirty. I kind of figured it would be a little cloudy, but we had to make use with what we had living in an apartment. What I didn't expect was even after I gave it a chance to clear up, it continues to be terrible and I'm a clean freak. And when I mean clean freak, I mean ocd cleaning even the tanks at work with a toothbrush. Customers chuckle and always comment how immaculate the tanks are and how they've never seen someone sit there and scrub corners and spots so meticulously and often. This sand has been an ocd nightmare, I don't understand how I put up with it for so long.
