hey bro last nite I was up till 3 jacking around cleaning house, jamming a bit, and making a video of me taking apart my whole bowl and washing out the sandbed with tap like you did, then putting my reef back together with no cycle and the corals were open within an hour. I now have an age-reset reef, its age went backwards in time due to the loss of detritus Id let accumulate by being lazy exporter.
Thought this was worth posting because if we polled the 1000 people posting on this site, exactly 2 have rinsed their live sand in tap water and then immediately used it for a living reef. there are 2 rule bio breakers around here, be ware lest this catch on ;)
I would have waited till Thursday so you could see it in person but my bowl was scummy and last nite was the drop, is now reset to brand new. my corals sat on my counter, in the air, alone with my live rock for nearly 20 minutes. zero recycle, zero loss, pods and brittle stars and crab is back out feeding etc. its all on video am mashing it up now for post later on
