Well the end of the year has gone well. The koi are doing great and still feeding most days due to the elevated temps. The nets/covers are now off since the leaves are gone. The water clarity is insane.... you can see every little detail on the deck in 2m. The temporary floating skimmer has worked a treat. I picked up a pond vacuum a month ago and gave the bottom a good clean at the weekend which means there's no detritus for any nasties to hide in ready for the spring. It's a real shame I can't post vids on here as I have some great footage of the koi milling about.
So now I need to plan for spring which apparently is the most tricky and dangerous time of year. Parasites wake up before the koi so it's essential I do everything I can to keep their immune systems working as well as possible. If you lose your water parameters early on, you're chasing your tail all year, so I have to be bang on it to stay a step ahead of any issues with algae, weed, DO, and ammonia, nitrite, pH etc.
Really enjoyed the last few months and looking forward to my first full year with the pond. Looking to feed heavily next year to get some good growth, while maintaining the water quality. I'll keep this thread updated from time to time for anyone that's interested.
