So I added some dry sand to my tank last week, rinsed it for hours so the initial install to the tank had minimum clouding. Let everything settle down real good, waited a few days with the filter running which didn't move the sand at all and decided to try my power head out to see how the flow would effect the sand... BAD idea. Instant dust storm. Is there any way to mitigate this? Do I let the power heads run till the sand stop moving in certain spots or do I wait till the dry sand cycles to firm up? Tank is already cycled.
