Another great video Magnus. I worked in aquaculture for about 15 years. I Built and then worked on the management team at 2 of the largest indoor farms in the US one saltwater and one fresh. Both facilities used almost identical systems in the nursery sections minus the bog. The saltwater farm used a settling pond with no plants to process NO3 and the freshwater facilities uses what is essentially an anoxic bioflock system with a masive membrane filter that is to complex to diy. I think you have built a time tested and reliable system. A question for you dose your water temperature change around the same time as you see the increase in NO2? I know the nitrafying bacteria will shift what species is dominant at a few different temperature points as well as the availability of oxygen for those bacteria. Just a thought maybe your bacterial colonies shift as the water warms up.
Thanks mate. Wow! What a quality coment! My background is from public display aquarium and exeperimental indoor aquaponic plant. Not formaly educated but been working with some of the best in their speciality. Biology, water chemistry etc. I like your theory, it clearly shows that you know what you are talking about. In this case I don't think thats the answer. The months around mid summer is the most stable temperatures, ranging between 19-20c. I have two possible theories that may cause it. This time of the year I feed a lot of high protein food. It may be the case that the filters just can’t cope with it? Obviously this built would solve that. The other possibility has to do with awailable sun light. As light increase in spring and early summer plants grow more and more and use ammonia before it gets into the nitrogen cycle. After mid summer sun and photosyntesis decreases slowly and filters have to deal with a constant increase of ammonia. Like the filter and the bacterias is in a constant startup dealing with it. This would be solved with reducing the plant mass in spring. I would prefere not to do that as I think the bog is so beautiful in summer. So excited to see what happens the next few weeks. It will determine what is the next steps. 😀👍
@@greenmachinesweden I suppose you are probably correct. Just a mater of the filters needing to evolve with the changing load they need to deal with. If I remember correctly from one of your earlier videos the increase in NO2 you experience wasn't extreme just an measurable change. Not enough to lose sleep over. I also agree with you on the bog it would be a shame to cut it back or thin it out. Anyway it is cool to see we share another common interest.
Indeed. The levels is low and no big issue. But no harm in trying to get it to 0. I just don't know what would happen if the upgrade was not done as bioload increase.
Super job buddy, verry clean! Love that I was thinking OH damn no security mesures, not 2 sec later Anna brought them to you😂🤣 super Anna! Really like those flow meters, if It ever re do my pond I will defenetly add those in there
Thanks for the sub and the view mate. I am glad you liked it. I do prefere to nitrify amonia before gas off as my bog is so hungry for nitrogen. But in the heat of summer my bead filter is just not enough.🙂👍
Hi Buddy, fantastic job you did a fab job looks great. I like the slits in the pipe might use that idea myself, should really enhance your filtration. 👍
Thanks for watching and comenting. I don't think that there are any correlation between colour and type. This one is floating type. It is manufactured for waste water treatment. 😀👍
I am not sure evolution aqua is manufacturing K1. I would think they just brand generic OEM material. But not sure. This ones came from a food fish production facility that went out of business. It was never used. I have been told it was from a brand targeting the waste water treatment segment.😀👍
The filter don't produce nitrates. Just converts amonia and nitrite to nitrate. Given same fish load, feeding and kno3 adition there will be no difference in awailable nitrate for the plants. I just hope the small nitrite levels after mid summer will not happen again. Future will tell. 😀👍
Hi Magnus, will check you later as am going out. Do you think Jelle ‘s channel is being hacked? He’s getting some well weird comments from ‘random’ names! God bless you 🙏✝️ ✌️🇺🇦🌻🙏
No worries my friend. This one is quite technical. Almost half of my subscribers are Koi enthusiasts, but it may not suit the bonsai subscribers. I get weird comments with strange links all the time. It does not mean one is hacked as commenting is open to everyone. I just delete them as soon as I see them.😀👍

@@greenmachinesweden Absolutely.
Great idea for extra filter thanks for sharing
Thanks! It has been running for 2 seasons now and works great. 🙂👍
That is excellent.. Great job
Thanks Chris, I am happy you approve. 😀👍
Hello my friend. Great job buddy. That looks nice. Like21
Thanks mate. I am so happy you liked it. 😀👍
Sorry late on this one.. Didn't get notification again but didn't want to miss the moving bed filter
No worries mate.😀👍
Wow
Thanks for watching and commenting. I am happy you like it. 😀👍
Great job buddy. That looks nice.
Thanks Sid. 😀👍
Looking forward to it.
😀👍
Looks like a good job, well done
Thanks mate.😀👍
Super job buddy, verry clean! Love that I was thinking OH damn no security mesures, not 2 sec later Anna brought them to you😂🤣 super Anna! Really like those flow meters, if It ever re do my pond I will defenetly add those in there
Thanks Cedrik. Yes, Anna is the one to spot safety issues and correct it. I am happy to have her. 😀👍
Just subscribed mate 👍 I think moving bed filters are a must for any fish pond, I find it helps gas off the ammonia.

Well I think you’re a genius Magnus, lovely job, you looked justly pleased 😊👏God bless all your endeavours 🙏✝️ ✌️🇺🇦🌻✌️
Thanks a lot Gaye! Hope you had a nice evening out. 😀👍.
Yes thanx n nice to return to your vid. My RUclips Day began with Jay’s build n ended with yours, Brill, right up my street !! ✌️
Hi Buddy, fantastic job you did a fab job looks great. I like the slits in the pipe might use that idea myself, should really enhance your filtration. 👍
Thanks mate. Yes I think there will be no more need for upgrade, ever. 😀👍
You da plumber man
😀👍
I thought the black / grey K1 was a sinking media for a static bed?
Thanks for watching and comenting. I don't think that there are any correlation between colour and type. This one is floating type. It is manufactured for waste water treatment. 😀👍
@@greenmachinesweden is it not the one manufactured by Evolution Aqua Kaldness K1?
I am not sure evolution aqua is manufacturing K1. I would think they just brand generic OEM material. But not sure.
This ones came from a food fish production facility that went out of business. It was never used. I have been told it was from a brand targeting the waste water treatment segment.😀👍
more nitrates for your bog plants?
The filter don't produce nitrates. Just converts amonia and nitrite to nitrate. Given same fish load, feeding and kno3 adition there will be no difference in awailable nitrate for the plants. I just hope the small nitrite levels after mid summer will not happen again. Future will tell. 😀👍
