curious about your clouding timeframe expected
what are your plans to not cloud up the new tank? I have about five threads immediately handy one is a guy who literally turns his tank into brown mud, hundreds of dollars in coral in tow, and his post is asking why he did that, shocking
he's posting about why would he take a running reef tank cruising right along and turn it 100% opaque, his post was sort of a venting about it all. taken as a warning by me
so there's an option to not do that to your system, are you choosing that way or the milky way
the thing about sand pre rinsing, knowing exactly what your sand will do before you take guesses with it, is that many folks don't want you to do this. they demand, demand you add the sand for the cloud effect and ride it out.
their rationale is you needed the bacteria in the bag, that your tank was not just running fine without them.
you have the ability to add snowglobe clean grains to this tank, and offend it 0%
and any sand you can't rinse to that control level is too fine to use in anything but a lagoon setup slower flow. pre rinsing lets you assess what wet grains do, vs adding a huge mistake to a great running tank.
