a lot of us old school aquarists never feared tap water, we came from an era where fear of bacterial loss was not a factor in aquarium keeping
I always rinsed out my filter pads with tap water vs RO water in my freshwater setups, we just never believed a brief rinse in tap would kill anything since it never harmed us slurping it up copiously through various garden hoses as we ran among homes in el paso in the 80s lol.
to the benefit of bottle bac sellers nowadays, that old school tenet has been squelched, everyone fears bacterial loss-they will click to buy a replacement peace of mind
its one of the prime reasons I want to keep not using bottle bacteria here/sets the market fairly straight.
readers can see: if the meanest thing you could do to a reef tank still doesn't require new bacteria, what does require it> unmask the truth that the sellers withhold
the other customizations such as never adding any old sand (the 1 handful as a seed source routine) and always re-ramping lights are further developed means of stopping losses as we've evolved. the goal was to write a work thread that a new tank transfer/sandbed swap customer could replicate solely off the examples and patterns, without needing a customized setup.
if we let people add 1 handful of sand in a tank transfer, because someone else did it, their tank dies 1/500 jobs like this one:
Recently had a huge leak in our 90 gal reef which forced us to upgrade sooner than expected . The upgrade being a 230 gal with a 48 gal sump . Mistake #1 I added some of the old sand assuming it would be beneficial to have a little bacteria .. I was wrong . Nuked the whole tank killing all fish...

Rcm I need to use your link because there's an uptick trend in the recommend to add 1 handful of carryover sand, it helps people actually see why we should not do that
ensuring the new / receiving tank is 100% cloudless, all sand and rock is cloudless so that we assess success by clean water, is part of the evolved methods we arrived at here on year 8.
out of this entire thread, the only 2 losses I recall were fish jumping out of the holding tote. we are at 100% safety rate in all displays after rip cleans, not on just this thread, everywhere. rip cleans are on all major forums except reefcentral, they're not into evolutionary changes within the hobby lol.
also by this thread we can see that sandbed bacteria, once claimed a vital link in all reefs, simply aren't
sandbed bacteria and their complexed waste are
bioloading only you don't get to enjoy it like we do with fish bioloading. sandbed bacteria use up some oxygen, they output collective waste gasses, they emit acids as they reduce substrate to gain feed/this is bioloading. this is why pent up sandbeds require fifty pages of special techniques to have safe outcomes, we are dealing with bioload when we deal in sandbeds.
reef tanks
tolerate sandbed waste and bacteria; it's actually more beneficial to be free of the waste loading altogether/hence the success of bare bottom setups.
we also discovered here that reef tanks are better turned into bare bottom not by partial removal of sand in sections, but all at once, then with a light re ramping thereafter.
BRS tried to remove their sandbed, it harmed their tank, they skipped the light acclimation step. they're still juniors in the game, albeit rich ones / bottle bac sellers
