I don't put many (or any) fish in my systems, so the DT is fine after temp acclimate (float) for me. I drip acclimate all inverts, shrimp for as long as I can (2-3hrs usually).
For coral I temp acclimate (float) then put in a bucket with shipping water, adding 25% tank water, then 25% tank water 15m later, then 25% tank water and remove 25% bucket water to drain 15m later (do that twice). I add dip to the result (ReVive) at half-dose and agitate for 5m then place in low flow / low light in tank. Turn lights off if coral is coming from overnight shipping.
