What I was referring to was the basic "float the bag, then add 50% tank water", etc, etc, etc.
These days I have found the best luck with my feeder fish by following a similar concept. Let's assume that I am taking them from the holding tank and putting them into the aquarium to eventually be eaten, and that I'm doing it with 2 dozen minnows:
I just start out with 1g of their water in a 5g bucket and then add 1/2g of the future tank water every 10-15mins. I repeat this until the 5g is full. Empty out all but about 1/2-1g and do it over. After that they are Good to Go. They still stress, but I have learned that by shutting off the C02 for a few hrs and aerating the future tank--they stress much, much less.
Holding tank specs: Gh 18, Kh14, pH ~8.0+, TDS oftentimes 500, Temps this winter 63-65F
Main Tanks: Gh2.5, Kh1, pH ~6.0, TDS -200, Temp ~85F
As You can see there are drastic differences in the tank/water specs. The Main Tanks are 100% RO and the Holding tank is currently Tap.
Main Tank-Heated. Holding Tank-Unheated.
When I have used the drip-method I found that the Temp would never rise up to the tank (even in a different setup where temps were 82-83F) and the fish always severely stressed from the C02 or pH difference. Since I have started using this "Method" and turning off the C02 and aerating--the difference is completely noticeable.
I am not really trying to suggest anything here. I am just really trying to share my experiences and what I have learned over the last couple of years dealing with literally thousands of fish. The method that I use now works best for me in my situation--including the particular fish that I deal with. There may be some food for thought here for others.
