the coolest trick is the tap rinse on a running reef, ye do over.
Can do, it does not cause a recycle whatsoever. so if anyone has a nano or accessible tank or just wants the bed cleaned, can do. we'd take apart your entire reef, hold corals rocks fish elsewhere, clean the sand outside the tank in tap water until 100% clear, then ro final rinse, then back in.
stack it all back in, it doesn't cause a recycle because sandbed bacteria are extra above what is needed, like running 6 extra canister filters. You can do that on any reef, harmless extra surface area. and when it comes time to remove them, or tap rinse them, that they're extra is why it doesn't matter.
the risk in doing a sandbed cleaning on a running tank is under-doing it, not the actual rinse. people rinsing only halfway/partially out of fear of bacterial loss causes losses, whereas completely totally blast-cleaned sand like a snowglobe cannot cause a recycle, its only sandgrains. if there is aged rotting detritus in the sandbed that's the dangerous stuff, a newish bed is no prob
Im not sure how those links could be read, the ones saying the clouding has lasted ten days pls help, and still recommend no rinse
