Wow, so cool you've been interviewed.....hope it's published
Good news on getting pump prob diagnosed and replaced and even better news the bog did such a good job.
You might not know that I recently decided to rehome our 4 adult koi.....I did a little thread on it. It was an emotional decision, but end of story, they are living with a koi breeder and once out of quarantine ( that pond is about twice the size of ours ) they will retire in his huge pond with some 30 + year old koi.
Your pics are beautiful, your koi are so colorful and growing !
