How long does it take for sand to settle in a new tank

[drd990]

I just set up my new 20 Gallon tank with sand. The water right now is very murky and I was wondering how long it takes for this to settle. Does it matter if I run my pump and/or heater while waiting for it? Not sure if that'd speed it up or slow it down. Any help is greatly appreciated, thanks!

I Am going to go out on a limb here but i think its going to take as long as its going to take. a little tip. put your sand in your new tank add news paper over the sand slowly add the water into your tank wait a few minutes and remove the paper of course. BTW heater yes pump ummmm not a good idea

If it's fine sand usually takes over night unless you can run some mechanical filtration.

It took a couple days in my new tank.
