I put play sand in my 29 gal tank 2 days ago and it doesn't seem to be settling at all. I rinsed the sand a billion times but the water is super dusty and hasn't cleared up at all. I put the same sand in my 10 gallon and it cleared up in a day. I do not have a filter yet for the 29, it will be her tomorrow hopefully. Is the dust not clearing because of lack of filter? Any help is appreciated, thanks
