This is what the diver recommends for acclimatization of his fish,
Acclimation:
the most important part of receiving fish after a long transit time is proper acclimation. This will determine whether or not you fish has a long happy life or dies shortly after.
During long flights, the PH drops considerably. Most of the time it drops to around 7.2-7.5. In extreme cases it will drop to below 7.0 (fish pooped in the bag/small bag etc)
Drip acclimation is the only sure way to regulate the amount of water going in the bucket and the speed. The speed is very important. 1-2 drips per second is recommended. The PH and salinity cannot be raised quickly without ill effects, so please do not add water to the bag then dump some out then add some again...
Add the water that the fish arrived in into a bucket/tote etc. (5 gallon buckets work well) For those of you ordering more then 1 fish, seperate buckets is a good idea to reduce stress during the acclimation process.
Run an airline tube from the main display/QT tank to the bucket/tote. Tie a small knot at the end of the airline tube so the water is "dripping" into the bucket. Again, 1-2 drips per second is plenty fast.
This drip acclimation should be done over the course of 4+ hours, with constant PH checks.
It is a good idea to check the PH in the Fish's shipping water and the display so you know how high you have to go.
ONLY introduce the fish to the display/QT when the salinity and PH are both EQUAL. A rapid increase in PH or salinity will have negative effects on most fish.
IMPORTANT!
The salinity in the bags will be around 1.016. this is on the low side. Make sure you drip slowly for salinity increases as well.
For large fish, airstones may be needed to replenish the oxygen lost during transit. (not to much air)
cover your buckets! Fairies/dorrybacks/triggers love to jump!!!
