While I'm not a fan of everything in this world I am a fan of people having the pond they want. If you're happy, I'm happy.
As far as getting your pond ready for fish there's many things different people suggest. Some of these would include:
Some people say to jump start the bio filter by adding ammonia and waiting for ammonia and nitrite to go to zero. Some people say to use feeder goldfish for this and then kill the fish when done.
Some people say to let the pond run for a month or more to let it "balance".
Some people say to add different kinds of bacteria.
Some people say to add barley straw, or pellets, or extract, or some combination and let that rot for a 6-8 weeks so you won't get algae. Some people say this can be done with the fish, others say it can harm the fish.
Some people say to pH buffer the water so pH is stable when fish are added. Some people say to use baking soda which works instantly. Others say things like oyster shell, limestone, plaster of paris, etc., which all take longer but which supporters say are safer.
Some people say to wait until your first algae bloom is over before adding fish.
Some people say to make sure the pond surface is 40%, 50%, 75% or 80% covered with plants first.
Tons more I assume.
The only requirement I would say is to remove the chlorine with a chemical or wait until the water tests zero for chlorine. Not everyone does this and many fish do live through the process depending on how chlorinated the water is and how clean the pond was.
