Just to recap in case you never read the first thread.
My first step from a water feature to koi pond did not go well.
I had read alot but very little actual experience. Don't believe everything you read!
The more I learn the less I knew cannot be understated. Also I would add I did not have enough knowledge to even know the right questions.
I did a few road trips, talked on the phone and reread most of the books.
Finally I might have it right or close. You decide.
