Replace media tower aio with filter floss holder

[necbov]

Hey everyone I wanted to replace my media tower (to remove the gray black and green factory sponges ) and put only filter floss. I found something online and made it to my desired dimensions for my aio 90l tank 3 chambers so I put it in the middle . The problem: too noise and too much bubble oxygen inside the tank from return pump . It’s like raining in my tank and room. (Video bellow) so my question is : can I make a department bellow to add a second filter floss (like silencer) and then the flow after the filter floss holder will be going only to the corners?! Have anyone tried that ?

Once the water level goes up in the return chamber the sound should be gone! Adjust the float switch location if needed.

For some reason (I’m noob either my physics is bad) when I adjust the water level in The last chamber(3rd with the return pump) the tank water level goes up (like very close to the edge of the top). I believe only with the media tower full with sponges etc the water level rises in the middle. Or I’m wrong

This is what I mean. But I don’t know if it works or what other option I have

Sounds like the overflow can’t handle the flow coming from the return pump? Try to turn down the pump a bit, or add a flow adjustment valve?

I’m not sure how your AIO chambers are designed but usually the 2nd (media) chamber has the same water level as the return chamber.

For silencer: something like you drew should work (a bit hard to see the bottom side), or something with multiple stairs could also work

That’s what happens, it’s my bad because i put a very strong return pump dd funktion 4000 (but in the return hose I have already put a flow adjustment valve in case it was too strong but I forgot it).

From other photos I saw that’s it’s correct both 2nd and 3rd chamber is the same level .

3d print: I put at the bottom an extra flat square minus 3mm and 4 mm for each side so the flow direction is the wall of the chamber and not directly down.

I’m interested also for the stairs that you said , what’s would be the best position?!

 

[necbov]

I don’t want to compromise the flow too much because I want it for oxygen (surface agitation)

That’s indeed a lot of flow from a return pump!

Sorry for the bad doodle, but something like this: (cross section)

Ppl do spiral as well sometimes

Once I get home I can try to draft something up in Fusion ;)

Btw, the height of your float switch and optical switch need to be lowered as well, once the ATO kicks in the tank would flood your room, based on the your description.

I think it would be safer to lower the return pump output (and supplement flow with a wave maker), or remove the weir on your overflow to see if it can handle more flow.
