How would a much more fine sponge work for mechanical, I wouldn’t have to replace it right?Mechanical filtration and biological are two different things. I don’t think there is one filter that does it.
If you want a cheap filter just buy a aquaclear sponge, cut it to size and stuff it in there. That would be the biological.
For mechanical you could buy some filter floss and use that as your mechanical.
I have a 10-20 gallon HOB. Little space for something to maintain bb, so I bought a small media bag and put half a handful of ceramic rings in it to float. Now I can change out my flossy cartridge without crashing my cycle on my 10 gallon.
Customize your filter here...
