Eyes and tails starting to form on day 3.

Eyes and tails starting to form on day 3.
Bought brand new and I'm told I'm the first person to open it. Thermal paste and liquid metal everywhere. Worst I've ever seen. Someone has put normal compound on top of the liquid metal and then pressed it down. It's pushed liquid metal onto the motherboard, around the edges, and gave my customer terrible thermals from day one.

The red ghostie in the foreground used to have an orange head and completely silver body, so we called him Mask Jr after another similar fish we had before him called Mask. Over the years his body has gone blood-red.
Basically as the title asks; I'm looking to hear how much people invest in fresh water for their ponds and what sorts of costs associated they're happy with.
I have a 18,000lt indoor pond. It has a very robust filtration system but no plants, no bog filter, and no anoxic filtration. I've generally kept water changes down to only topping up as needed, and topping up after cleaning the filters out etc. I'd average somewhere between 1-5% changes a week doing this.
I've never noticed issues and my old (aging) test kit showed everything as fine, but after recently installing my underwater camera (live feed!) and watching them daily, I've noticed that they are flashing throughout the day which prompted me to get a new test kit to ensure the results are what they say they are. Well the new kit shows zero ammonia and nitrite, but high nitrates (as you'd imagine), with everything else as it should be.
I've treated the pond with Klear to help bring this down, but need to sort some plumbing to allow easier and more regular water changes without it being a laborious job. The plan of course is to keep nitrates at a better level (ideally closer to 30-40, and not 60+mg/l which is where I am now).
This is looking to double my water bill and get me to around £100/m, on top of the £50 a month on food and filtration. And they say fish are low maintenance!
TLDR: So it got me wondering; what sort of water bills are people looking at, or have they built enough natural filtration to naturally drop nitrates to manageable levels?
For those who were interested in seeing my live stream - I've got it sorted and it's seemingly happy on it's little dedicated server.
Let me know if I can improve it anyway. I've got a simple loop of the room's ambient noise going so it's not just completely silent, I think this is better than nothing.
Enjoy!

Used ChatGPT to stylise a 10 year old image of my fish, then upscaled so it'd print nice and crisp at A1 size. Used my Stylus 7800 printer to print the thing - I thought the end result looked good enough to share. Sorry if this sort of thing isn't allowed here.
I've seen a lot of people's bog/drum/DIY setups on here, so I thought I'd show mine. I run 5x 154L tubs, first is full of brushes, second full of alfagrog, third is a moving bed with about 100lt of K1, the fourth is a settling tank which houses a large bag of crushed oyster shell and the first pump, this then goes up and through a 55W UV before hitting a 4-stage shower filter full of sintered glass, and finally into the fifth tub. The fifth tub is also a settlement tank, which has a protein rise running and the final pump which goes through a 37W helix UV, and ultimately back to the pond via the 90cm blade.
Water parameters are solid, although being an indoor pond without plants does mean I need to supplement it from time to time to keep pH / KH and the like in check.
Couldn't tell you quite how much this filtration setup cost. Certainly less than a drum or branded filter, but still not particularly cheap either all things considered.
The pond is still very much in the works, but getting there now.
Many of these have gone now, but I believe a couple of the ghost koi are the same ones alive and well today in my pond. I know I have at least a few over 30 years old. Not the most interesting video on the sub granted, but means the world to me to find while archiving old 8mm tapes. I lost my Dad in 2020 to cancer and these were his beloved fish. I built a pond in his memory soon after he died and moved his fish including a couple from this video into it. We have a few pictures of the pond from the 90s but I believe this is the earliest and possibly only video from back then.
"My babies!" he'd say proudly.
Hope this is the right place for this post. I simply tried to stack some images to get a clear image of the moon (or as clear as 200mm can do) but didn't have my layers aligned and accidentally made this.
