Hi guys I set up my new tank 7 days ago I washed through my sand. As I filled the tank up the water remained White and milky straight away over the days it has cleated a bit. I think it is from maybe I did not wash through my sand enough and was wondering have I got to empty the tank right out to clear this or can I do something else to clear it ,oh I used some stuff to try and clear the water with no joy. It's a jewel rio 240 and I'm only using the jewel filter. Any help would really be appreciated cheers
