Welcome! You've definitely found THE spot for information on pond management and growing fish.
Looks like you're well underway on a fun project. If you ever feel like you're getting in the weeds on the pond construction project, there are a lot folks on here that have forgotten more about moving dirt to make a hole for water than I'll ever know. Best wishes and welcome to the forum!
If you haven't already, you should consider subscribing to Pond Boss magazine. It is a valuable resource... you'll be glad you did!
cheers,
Clayton
