Two suppliers I've used recently explicitly warned *not* to drip acclimate - biota and reefcleaners.
I've always been a little skeptical that fish are so sensitive to salinity changes. A popular treatment for flukes is the "freshwater dip" where we drop a sick fish from normal salinity directly into pure freshwater for several minutes. Most fish tolerate this very extreme salinity change, even when infected with parasites. The difference between salinity in our tanks vs suppliers is likely to be far more subtle. I am less certain about pH, which maybe could have an impact? I just don't know.
It makes more sense to me that inverts would be sensitive to salinity changes but reefcleaners states in very certain terms not to drip acclimate. Their protocol is really simple- temp acclimate the bags for 15 mins, then drain/net and dump 'em in. I have purchased inverts from reefcleaners several times, following their recommended protocol and usually the livestock is fine. Exceptions were one little tux urchin and several trochus snails, but I got a lot of other snails, chitons, limpets and crabs that made it.
I think some suppliers still recommend drip acclimation, so if the supplier recommends that's what I'll do. But I can't help wonder if anyone has a clue what works best.
Is there no standard?
