Any size available possible.. 🙂 i did it with the smallest.. And it works.
still had a Co2 hose connector with M5 thread and a air stone. Did saw off the hose part from the air stone and taped a M5 thread in it.
Did the same with the bottom of the HOB filters sponch compartiment, screwed the hose connector in and the little thread sticking out in the filter box i screwed on the airstone.. Did put the sponsh on the inlet in the tank as prefilter. In the filter i first tried sand, that doesn't do the job. Got me some K1 filter beats from the LFS and this does the job. Filled the filter for 1/3 with those beats and toped it off with a smaller piece of sponsh.
I made a little video of the result.. 🙂 i did it the fancy way again, because i do not like kit. but with drilling a hole and seal it with kit to connect the airstone should be good to go as well. Functionaly it's the same thing.
Never mind the sand still in there, doesnt hurt. It is all made this afternoon.. So the beats are not colonized yet.. If they do they loose a bit buoyancy and will swirll around a lot more than they do now.. But this will take a few weeks. The idea works thats the whole point after all. now the mechanical sponsh part is in the tank and the bio in the filter..
Here is my small nano fluidized HOB filter.
oh in the video you'll see a ball shaped airstone i thought that would do better. The above is example but should do the same.. 🙂
