Well, first the bad points of the year...
1)I had a health issue with the koi in my main in early spring but that was taken care of and no reoccurrence
2)Had a huge tree removed by my pond which took away from koi funds and while they ground down the root a wood splinter punctured my liner. I did not notice until weeks later when suddenly I was losing a lot of water. Water pressure had made the tear into a huge hole. I am still working on it.
3)Had one jumper and one heron stab victim
Now the good points
1)Learned how to inject the correct way with the onset of the health issue in spring
2)With tree removed, I can look forward to buying/installing a vortex chamber after seeing the difference it makes
3)Growth rates were good for the most part. I started feeding high protein in mid June. Some koi grew from 8 to 12 inches, others from 11 inches to 17 inches to date. This was the first time I kept track of growth rates. Skin quality of koi hve improved.
4)Despite having 1/3 of main pond drained right now, water quality is still ideal so I know biofilters are mature even after 2 weeks at running at 2/3 pond volume
5)Had unplanned spawning. Fry are now 3-4 months. Learning a lot from the experience.
6)Learned the benefits of a using a proper filtration system firsthand when someone helped me set it up
