I could literally write some sort of an essay on how much I have had to mess with my HoBs to get them to function and "fix design issues".  I have always enjoyed this aspect of the hobby and I'd love to ask everyone about their setups. For reference below, I'll toss in a few pretty epic videos when it comes to filter setups.

Please feel free to post and share your filter setups here!
 

 

I'll have to grab some paper and sketch out a few mods I've done!

This is the most recent one for me.  Replacing damaged sponge off the Ziss Bubble Bio Moving Bed Filter and adding a fine filter foam to help keep the media chamber / air chamber from filling with gunk.

Another way to perform this is to use actual fine pad cut into a circle and only the black foam (bumpy side down)

This is the original, replacing it because it's tearing on both sides right in the middle.

This is the new one, bumpy foam, stacked with bumpy side facing each other so it fits in the filter.

Edit: More mods to the ziss.  Trying to buffer my water without adding it to the substrate (black substrate)

I have a Co-op med sponge filter in a 20L.  Any ideas on how to temporarily modify it to have a fine polish pad?  Trying to filter out some finer suspended organic material (probably decaying plant matter).

I went the internal filter route and it worked well.

Update…I used a Sicce Nano Micron internal filter ($20 on Amazon).  I didn’t use the provided sponge, but used some blue filter floss and a polishing pad (left over scraps). The tank looks better in two weeks, and much less floating particles.  I already rinse out the media too as it clogged up pretty fast.

Marineland Penguin Biowheel 200 (sans biowheel) 🤣


Bunch of detritus was being washed back out in the tank. @nabokovfan87 helped me resolve the issue and this is the end result.

Inflow > seeded floss > water flow in back > new coarse sponge (gap under it) > new filter floss > seeded ceramic media (fully submerged) > coarse sponge in outflow to dampen sound (placed UNDER the lid).

Also the tops of sponges are above water level (except for those first seeded sponges at inflow- those are submerged). 
 

Works great, no more detritus piles.

The Aqueon Quietflow is literally the same exact thing but the pump is on the opposite side!
Marineland Penguin filters are also the same exact way and you can mod them the exact same method.
Tetra HoBs as well flow in this pattern and have this same general setup.
 

Hopefully if anyone is trying to figure out how to mod one of those, they can easily do it now with confidence!

@nabokovfan87 you are like a filter encyclopedia.  😆  Does your employment relate to anything mechanical, bychance?  Seems you love tinkering.  My dad & brother are the same way. They go "curb-shopping" in the neighborhood and find vaccum cleaners, paper shredders, air compressors, or whatever people are throwing away - and they fix them up!

I used to work in aerospace, airplane seats.  Went to college for computer engineering.  Filters were "easy" for me to understand in terms of just how to fix them. 🙂

That's awesome.  Recycling at it's finest!

You already know what my mods are. I learned from the best. And I have to say it was very simple and only took less than 2 hours from taking it off the tank. Cutting and filling in all the holes.

Updates on mine, I'll have to toss in the thread, but.... Yeah! The worst part is just waiting for the silicone to dry.

If you have any of these or the Marina/fluval hang on breeder boxes, Mark drills a hole in his to open up the intake and stop things from clogging due to the design issue. Very, very good idea, but please don't use your hands to hold parts and drill them. Use something a bit more secure and keep your hands out of the path of injury!

If you have a small file, that works too!
