Thanks for posting pls take succession pics those increments are helpful to see in pattern
the liferock is neutral impact, surfaces will begin to take on bacteria immediately after association with the other live rocks brought over.
swish as practical per rock the sand is the real locus of waste, clearing rock pores is just nice topping for all the effort so whichever is practical is fine for rocks.
* if I could summarize a hidden rule that runs all these rinse works it would be that no matter what we do to surrounding surface area, even half the live rock we all use will carry the full tank bioload immediately with no ramp up time. We have been trained to always fear lack of surface area but the opposite is true; we have so much beyond need we are free to rinse sand, omit it altogether in some builds, change it for new in many builds, add to or change current rock setup and it’s always going to skip cycle if the new tank is cloudless.
for example as a case comparative look at this instant remote DSB removal job. This is a -lot- of surface area adapted in the reef
I setup a removable deep sand bed in my sump 9 months ago but now I’d like to remove it to give me more room in the sump. What do you think the impact to tank chemistry might be and how to mitigate any negatives?

it only seems we removed a critical link to the systems filter area, but that only due to the prior training. When factoring updated cycling science rules he was keeping some or all of his current live rock…therefore what we removed ancillary to that was of neutral impact. In your case you are adding inert surface area to active, guaranteed safe.
we can take away from or instantly add to our common live rofk core and the operation will always skip cycle if the new setup is cloudless. No bottle bac used, bottle bac isn’t needed to rip clean, we rely on natural bacteria.
