Some more pictures - not anyone of the best but it show a Little bit of the Life in my Aquarium

I like how you have the flow set at a pulse.
Thank you, I might have to play with my settingsThank you all
I have done a lot of experiment in order to create this type of waves. Direct translated from Swedish - it is a standing wave or a seiches undulation. I moves a lot of water in my tank and the motion is all over the tank. The tool to create this is the pulse on/off duration - its different in every tank. I use a pulse of 0.7 seconds (on and off).

Thank you, I might have to play with my settings
Tack, kanske jag har att spela med mina inställningar
Thank you the lessonSwedish lecture: Jag måste kanske leka lite med mina inställningar
Swedish frequently has inverted word order compared to English - as you may have noticed on my way to write English. It often becomes Swenglish.
The word play in English have different meanings in Swedish. You play soccer - du spelar fotboll . The children plays - Barnen leker. But I understand your translation
I have Jeabao wave makers and the new WiFi controller. If you have the old mechanical controller (with a turning knob) - you will find the right settings if you try to set the knob in a position between 11:00 to 12:00 (if you look at the knob as it was a clock) and have wave maker mood

Lasse, I love your tank because it looks like you just carved it out of a full reef and you have just a small piece of it...so cool
I do no think you can make a "selfplaying piano", because the bacteria that produces carbon sources (for instance methanogenic which produce CH4 from reducing CO2) also need carbon source for the respiration. The carbon that these methanogenic strains produce is a result of using CO2 as electronacceptors, but for that you need an external carbon source to be oxidized. Therefore I do not believe in making an eternal machine...I think you have to always add som external carbon to make this denitrification-filters effective. This based on the fact that the carbon-producing bacteria(read CH4 producing) are heterotrophic most of them. In some steps they can use H2 to oxidize instead of organic carbon(if i have understood this correct), but that H2 is in turn produced from other organic compounds which is oxidized, so I do not think you never can stop adding external organic carbon if you want to have an effective denitrification. I have myself a denitrificationfilter running since 10 months, and that is very dependent on external carbon. Of course some organic carbon is adding automatically from the water from the aquarium itself, but that is not so much because that adding is dependent on the input flow rate to the denitrificationfilter which is very low. That is probably not sufficient to feed the denitrificationbacterial enough. That is my thoughts but of course I can be wrongFast organic carbon like alcohol, sugar and vinegar can be used in different ways in an aquarium. The most common (today) is to stimulate the growth of aerobic heterotrophs in order to export nutrients. However – the old way to use organic carbon is to use it for the denitrification in anaerobic environment. (Without oxygen) A fast organic carbon is needed in that process. The most common ways to manage a denitrification process is to add this carbon source from the outside. However if the anaerobic process has been established for a while – there is other processes that are able to produce fast carbon sources like sugar and alcohol from the internal organic waste inside the filter/sand bedd. You will get a piano that plays itself with other words.

very healthy and natural looking:_)Picture update

Well that is excactly what i tried to say, you must import organic compunds to the filter in same amount that you wants denitrification. If the import of carbon source is not enough from the system you must add external. We all know that in a system with high N and P there is often a wrong index between C/N where C is too low. Therefore I do not think it is always so easy to only say that the carbon source from the aquarium itself is sufficient for enough denitrification. But I totaly agree with you that in your system when the DSB get the whole flow as input you have much higher chance to get enough carbon but that the future Will tell. Nevertheless I like your concept and biological thinking very much. Some aquarist lacking that thinking so I am impressed of your system setupI have a flow through my DSB – therefore it will be new organic matter to the DSB all the time. The two first steps of anaerobic digestion hydrolysis and acidogenesis -simple sugars (hydrolysis) and alcohols (acidogenesis) will be formed as metabolites.
These metabolites will serve as fast organic carbon for the denitrification process
Of course – there most always be a transport of organic matter into the filter and it must be anaerobic. But the thing is that you instead of putting in organic carbon from the outside – you will do the same thing with the waste that your system produce. Even a self-playing piano need an energy source – the energy source in this anaerobic system is the waste and sludge that are produced from the food. To make the intial load of organic matter below the DSB I have pumped a lot of skimmate into the bed.
This is not only a theory – I have done this for more than a year and a half in a fish farm– total denitrification without putting in any external fast organic carbon source to the filters – only organic matter from the fishes and aerobic breakdown products (bacterial sludge).
