So I started setting up my 40 gallon tank now that the last of the hardware is on it's way. Long story short, I'm using pool filter sand for the substrate. I rinsed it in batches before adding it to the aquarium until the water looked clear, added it to the aquarium, and then added some water and smoothed it out. Water got very cloudy and is still cloudy (though a little better) several hours later. Is this normal? Did I just not rinse it well enough? Would water changes help by clearing out the suspended particulate/dust or just hurt matters by kicking up more when I refilled? Lastly should I be good to run the filter (Aquatop CF400) while it's still cloudy? There's no noticeable particulate, just the cloudiness (I guess dust that I didn't get when rinsing?) but wasn't sure if even just the very fine stuff suspended would have any negative impact. I'm guessing this would help clear it up faster?
