I'm pretty new to the hobby, I was repurposing a previously used 20 gallon tank which hadn't had fish in it for several months. (filter was running the entire time though) I wanted to change the substrate to go for a different look, I removed the old substrate, added the new substrate, a coarse, not super fine sand, and the tank became very cloudy. I did rinse it beforehand, but all of my strainers had holes large enough for the sand to fall through, so I dumped the substrate into a clean bucket, and filled it with water and emptied it several times. Thinking about it now, this probably didn't rinse all the dust out of it, is there any way to get rid of this cloudiness without draining the tank and cleaning the substrate again? I don't really want to do this because of any beneficial bacteria that is still in the water from the tanks previous fish. Will the substrate settle down on its own within a few days, or is this my only option?
