IM 25g AIO build

I'm not advocating using Prime during shipping. Just to use it when the buckets arrive, and before/during adding aeration when you start the acclimation process.
Ammonia levels in fish shipment bags build up and my limited memory tells me I heard/read something once that reminds me about this;
Upon exposing the fish shipment to open air/added air can increase the level of ammonia to near/beyond toxic levels very quickly, and is why many fish shipments suffer losses immediately after arrival.

Don't remember fully what I read, but reminds me about adding Prime or AmGuard to an open bag immediately upon opening/during acclimation.
