Your tank looks great. What are you dosing? From your sump pics looks like you have an auto doser. Also, is that a calcium reactor? Next question, why are the koi in a cage? And what kind of filter is that? The big gray one.

I had a cage put over my koi when my little girl was born you hear of so many kids drowning in ponds and this one is 7 foot deep so when my girls get to about 8 I'll remove it better safe than sorry yes that is a calcium reactor but no auto I like to know what and when goes into the tank which is not a lot only red sea phosphate remover the sump is full of miracle mud and LR the koi filter is a nexus 300 with easy fitted and full of k1 media thanks for looking
