Would A Wet/dry Filter Produce Enough Air Flow?

[Ilya]

I've got a Top Fin 40 wet/dry filter. Would it produce enough air flow through out my 22 gallon tank so that I wouldn't have to use an air pump?

Bump. Anyone?

you wouldnt have to use an air pump anyways if you have a filter unless your water is really warm

That is not a wet-dry filter, it is a regular hob. If the waterfall creates some circulation, then it should be fine.

It's a topfin 40. It looks like a wetdry filter for me. And I think it does create a waterfall, haven't checked. The water intake tube (intake chamber) is much longer then where the overflow is. So in theory, it will create a waterfall, and maybe even a small top current.

Ah, I've got some info about it. Apparently the 40 represents 40 gallons. And that roughly twice the size of my tank! So no problem there.

Looks like the media is covered with water, so it isn't a wet dry filter. A wet dry filter has the media in air and the water trickles over the media (giving the filter its other name: trickle filter/tower).

As mentioned, there is no need to run an air pump. An air pump will not do a great deal to aid gas exchange on the surface and surface agitation is far better achieved by placing a filter or powerhead outlet towards the surface.
