This is my first journal, and also my first attempt at a Hamburg Matten Filter (HMF). After doing a lot of reading I was really interested in trying to make this filtration method work for me. I decided to try a small, heavily planted shrimp tank. From what I can tell this is one of the best filtration methods for shrimp and shrimp fry. There is a lot of reading material about this filter method, but the main take away is a massive biological filtration area. As for mechanical filtration, it is lacking due to the fact that in order to achieve the best conditions for biological filtration, water passes through the filter on an average of ~1-3 tank volumes per hour (10g will be cycled ideally about 25gph) however these numbers are not fixed in stone. There is a lot of conversation as to what the "ideal" conditions are, and I suggest doing some research if you are indeed interested. As for how I decided on my rate of flows...I really didn't. I crowd sourced a lot of my info, but in the end I went with the recommendations from Stephan over at swisstropicals.com. This guy sells the poret foam and uses this filtration method himself so he is a wealth of knowledge. He gave me his recommendations and I followed them. A 45 pore per inch (ppi) poret foam was chosen as it is less likely to allow a small fry to wiggle its way into the reservoir behind the poret. From my test run it also seems this size is quite good a polishing the water as well. Another aspect to this foam is that you can actually plant mosses within the foam and it will take hold. Granted, the more and more the foam is covered by plants, the more restricted your flow can potentially be, upping air pressure usually solves this issue. The foam can also act as a meal serving station for your shrimp, with food particles caching in the foam and easily available to fry and grown shrimp alike.

I really recommend this finnex LED light. Especially on this smaller size aquarium the light output looks amazing, I can't wait to see how vibrant the plants and shrimp will look in the tank.
I have not considered using CO2 on this tank and I won't be crossing that bridge unless absolutely necessary.
Flora (have not attained):
duckweed (grow for my RES)
and a red...I haven't made up my mind yet as to which.
I don't have many species listed due to not being able to remember every species I see on this forum. However, I do want to keep it to maybe 6-7 different plant species in the tank. I want to keep this shrimp tank heavily planted, but still fairly simple. A dwarf sag carpet is really appealing to me, and a local I found on this site has offered me a few to help start my tank.
I am not worried about getting this all done at once.
Fauna (have not attained)
~10 yellow cherry shrimp
I have not had much experience in shrimp keeping outside of ghost shrimp in a community tank (but I never think about them). But after reading more and more into it I like the idea of having a small heavily planted tank with a booming shrimp population. There is a lot of red cherry shrimp guides out there and from what I can tell it is not that difficult. Water stability seems to be the most important thing from what I can tell. I am confident that I will have at least some results from this tank, but as it started off as an experiment I will keep that attitude.
Filter ran fine during test; I stirred up the substrate and made the water very cloudy, and within ~30 min the water was back to pre-agitated clarity. I tried to capture this on my phone but the quality did not capture this well so I have left it out.
I have to make a few modifications to the set up after seeing how the material and tank functioned in my test run.
I will be going to Home Depot tomorrow for some aquarium safe silicone, some sort of plastic divider that I can use to create a lip within the aquarium for added foam stability, and try to figure out just the best way to rest the JetLifter with the poret. The way I have it now produces a lot of surface bubbles that splash a tiny bit of water onto the LED fixture. Not a huge deal at the moment, but over time I see that as a problem. As for why I need the lips within the tank, the poret was having a difficult time sitting horizontally in my tank without creating a bow. If I can create a small barrier to push it up against it should give it the stability I am lacking. I will also take some more detailed measurements to see if a bit of shaving will give me better results.
I am also going to look into how much it would cost to paint the pvc pipe black rather than the normal white, although this is a thing I can do at any time so I am not worried right this moment about it.
So far I am happy with this set up. In the next few days when I have the final mods done on the HMF set-up, I will hopefully be adding plants and beginning my cycle. To help with that I will using media from my turtle tank. I have a small canister filter that I keep mini media bags to seed aquariums with.
