Hooking up a air line to a Internal Filter

  • We are currently upgrading MFK. thanks! -neo
If your goal is for the internal filter to work more efficiently I don’t see how adding air will help.
Why does it clog so quickly? Lots of suspended particulate waste?
Perhaps you could change the density of the foam insert to a more porous foam so it doesn’t clog up so fast 🤷🏻‍♂️

Air driven sponge filters are great but have limitations and need to be set up right. If they're clogging quick you probably need bigger sponges and/or more of them and better air pumps. Small sponges are only good for small tanks and light bioload with low power pumps.

I really like the aquatop-180 sponge filters, they seem to have the ideal density and size to be useful in larger tanks and the design is very simple and effective.

If this is for one of those little wall hanging internal sponge filters than it's probably just being overwhelmed by fish waste.

I dunno i thought maybe hooking up a air pump to it would make it more powerful That's why i posted the question. I just took it out the box with the sponges it comes with. i bought this because a very respected you tuber recommend it. I knew i should of bought the Sicce Shark PRO 900.
Is there a sponge density you would recommend the ones the internal filter come with are pretty flimsy

I have sponge filters on my tank i have no problem with those my air pump handles those fine. I had 2 one in each corner of my 125 but i wanted a little more swim space for my fish so i removed one of the sponges off the sand and bought this internal filter as it mounts to the glass so fish have more room on the bottom

The air is inserted into the water after the motor. The air inlet is just for if you want to spray bubbles out of it.

I tried something similar which also clogged easily, but that was in a turtle tank where scales and much larger poop came into play. I only wanted it for a bit of flow in the area but ended up buying something that looks like that Since Shark but was a generic version of Amazon. These aren't the most advanced filters but if you have sand, do proper water changes, and aren't overstocked they can be fine and are nice and silent.

If it can barely put out water even with a clean sponge and it was advertised as 500+ gph I'd ziplock and return it to Amazon if you're still in the return period.

This ^ definitely. If it's rated for 500gph, the actual real-world turnover will be less, and will continue to drop as it clogs. That does indeed look like a small, underpowered filter that might work in maybe a 30 or 40 gallon tank housing small community fish. You don't mention the tank size or stocking, but if you have a larger tank, especially with large, messy fish or turtles...this thing is a joke.

And as mentioned above, the air is added to the filter through that air line shown in the pic, which is inserted into the output of the filter after the pump. The idea is to have the other end of the line outside of the tank, drawing air from the room and injecting it into the pump output through a venturi. No additional air pump is needed or desired. The little bulb at the outside end of the airline is just to hold a tiny bit of sponge or floss to act as a dust filter.

Keep in mind that when air is injected this way, via venturi action, you will actually decrease the water output of the filter. Can't say for sure, but I would expect that attaching an air pump to add more air...would decrease the water output even further.
