Does this filter require an external air pump?

Don't buy this filter. Replacement cartridges have been discontinued by manufacturer. But to answer your question, no it doesn't.

No, it is a self contained internal filter. If you want more water agitation, put it on the first notch on the clip, so it will sit higher in the water. When the water comes out of the filter, it will have more force to it so it will agitate the water which will put more oxygen in the tank. Just plug in with filter and you're good to go. This filter is best for a small (5 gallon) tank, with a low billboard (not a lot of fish). Only change the cartridge when it is falling apart(~1yr or so). You can clean the cartridge in used tank water when you do a water change, or treated water (tap water contains chlorine which will kill off the beneficial bacteria). For more info, Google "aquarium nitrogen cycle" or "how to cycle an aquarium".

Yes, the filter is in the unit. Air escaping from the rear is proper. That is the air being vacuumed up in the front, catching the debris going thru the filter and passing out the back of the unit.

No it doesn't. I use a portable 12V air compressor, pump, which is available via Amazon. Not too expensive.

No. It comes with an adaptor to fit an air compressor or air pump (air chuck).

Must have an external pump. Filter works great. I would not recomend back washing. Works better if you take it apart and clean it that way.

I didn't need an air pump in any of my 12 fish tanks. They get enough oxygen thru the HOB filter(s) I have in each tank.

yes it does. my camera flooded too! not worth the risk. there are better external filters that don't involve taking the housing apart.

Yes, you need an air pump. This diffuser is heavy enough to stay where you place it after connecting it to the air pump by air tube. I use two diffusers to really aerate my water.

External. This filter is places outside the tank usually in the stand. Hoses run between the tank and filter.

No, just the carb. Air filter depends on your application / vehicle, filter housing, etc.

No other filter is needed, you may want to get some air stones just to keep the water at the bottom of the tank moving though.

I don't think it's necessary. The filter is high up and not positioned down low near the wheel well.

No not necessary - it has an internal tank. I did not have any trouble with the item but it is small and may not work for a large area.
