Aqueon 75 HOB Filter Diffuser & Super Bio chamber

Hi, I personally tried K1 media but could not get it to work, it would suck to the bottom no matter how many extra holes i drilled. I personally prefer using wall-less 15% gyroid infil blocks as bio media, so you could it with that and just do once a year cleanings. it's a ton of bio media.

Recommended to not change the settings. there are small visual imperfections, but deal with it.
