Just wanting some input on this, as I had trouble finding contents posted by the Co-Op specifically on this equipment type.
Not sure if the Ziss Bubble Filter counts, but I was thinking something more similar to this (just as a reference):

Are they not talked much about because many of them have quality defects or user-friendly issues?
Or is it in the Co-Op's opinion that sponge/HOB filters simply perform better?
I like my HOB because it takes little tank space, but it sometimes makes a lot of noise by vibrating against the glass or creating a waterfall when water level drops. That's how I became curious on internal power filters, but I don't want to waste money...
