This leads to a build up of CO2 in the bags, which drops the pH. Ammonia also build up in the bags, due to waste. Somewhat serendipitous is the fact that as pH drops, ammonia becomes less toxic.
But as pH increases, it becomes more toxic.
If you say drip acclimate these animals, you run the risk of increasing the pH and increasing the toxicity of the ammonia at the same time. So many do argue that the shock from sudden change in pH and salinity would be preferable than the acclimation. For fish, this could be a reasonable argument. For certain inverts, snails and echinoderms specifically, I don't think it is valid. But for corals it may be OK. Corals can be exposed to air during low tides after all.
This information is 100% correct. Many times some fish are only in the bags a few hours. Some fish stores here in Indy get thier fish from a company just in IL. This means from being bagged, to floating in the tanks, is usually less than 5 hours. The amount of waste built up is minimal, and the pH change in the bag is also very minimal. Drip acclimating is great, but seems primarily for when you are taking a fish from Natural Seawater, to Synthetic Seawater. This is done LONG before a fish is introduced to some pet store 1000miles inland of any ocean. Just my 2 cents. There are reasons for different types of acclimating, and there is a time and place for each. "end of thread jack".
