I have been running a homemade filter in one of my terrariums and here are the images of the results so far on day 41. It has been running for 41 days with no water change, purge or filter maintenance of any kind and it looks excellent so I think I have a winning formula here If interested let me know and I will share the filter setup instructions along with a set of schematics.
