I mean, I guess you could just lie and say you did their method (Biota specifically states that not following their protocol invalidates their 7-day guarantee). Maybe I'm just too honest lol. I am wary of ammonia with shipped fish tho and if I did drip acclimate I would probably add Prime or something like that.Guarantee is live arrival- not how acclimation was performed as they cant prove method used. If fish arrives normal and healthy- By all means consider their protocol. Winter is a tough time of the year in general to ship
