I’ll add this
we have a fifty page thread about moving reef tanks among homes/ distance
and for fifty pages we don’t have a single tank lost to a recycle because we break from norms in all the tank moves: no dirty reefs are moved and certainly no full reefs are moved…they’re empty and cleaned at the time of move, that’s key to earning fifty pages and no losses. It was formerly thought that deep cleaning was harmful, it’s not, it’s regenerative
the opposite of what the masses thought turned out to be true.
the fact you’re moving feet vs miles doesn’t matter, clean reefs always transfer better than old ones transferring all their waste. The partial/full drain plus refill alone kicks up enough waste in the unclean reef such that it’s a true risk of wipeout due to upwelled waste clouds in sand and rock. Moving a drained but still hardscape-full 100+ gallons can break seals, mayhem as mentioned and that’s not even the biological risk portion.
the safest way you could possibly move that reef would be to copy what a loss free fifty pages thread shows, youd disassemble the tank to avoid breakage and you’d clean the rocks and sand before reinstallation because that’s the best method known for reef relocation. The way we clean sand is very, very unique and that’s why there isn’t more than one tank move thread on the web that uses other people’s reef as proof and for outcome tracking. If anyone manages a move thread where dirty sand and rocks are moved, massive losses would result in the first few pages. You might read several accounts of dirty tank moves, but none of them are from a public tank move work thread they’re from the keepers testimony only where getting patterns and outcomes isn’t easy.
*getting new water is the hard part, we’d drain off and catch 80% of your current water in brutes and reuse it. Cleaning the sand and rocks before they go back in the moved tank is the key strategy.
