Since it's a forty, you should consider a deep clean before you install.
Drain off 30 gallons clean into brute
Apply to the tank what we do for forty pages in the sand rinse thread, that without uv alone s about 75% likely to fix it based on collected works there, but if not you've got ideal uv coming, in the clean condition.
Put back the thirty gallons drawn plus new water.
Not as primary mass remover, but as sparse growback preventer. In no way does deep cleaning cause anything bad, we got to page forty with wins not losses on file. Starting in the clean low organic low mass condition is ideal alignment, wanted to offer it as a pre conditioning idea. There is no time in reefing a deep clean is harmful, we've mastered and logged actions.
It can help you edge against dinos for sure, and also the next typical succession after in-tank dinos kill which is massive cyano (source: dinos thread in nuisance forum)
Every type of reef in every state of prep is logged and half are for home moves. It means we're deep cleaning a perfectly good reef because they're moving homes, so they must part it out. They land on the other side with a cleaner reef than before... that's what we'd do to your tank. Any arrangement of corals isn't a concern, they all turn out the same with a few special tweaks. Our most recent on file rip cleaning beat dinos in one pass in the nanos forum here. Tokash23
