Is this a sump, or a quarantine tank? For a quarantine tank, I'm not sure what the return pump and pvc pipe would be for.
PVC pipe sections for hiding spots I assume?
yes
what kind of biological filter is needed?
If you've already got an air stone, You have everything needed to run a sponge filter, other than sponge filter which can be had for under 10 bucks. Unless you are planning on doing a total water changes every day, You are going to need biological filtration.
Fish are going to produce ammonia, so any seeded sponge filter will do.
would this work?

Looks like a air powered sponge filter ( needs a air pump) , very similar to what I use for my quarantine tank.would this work?
Luftbetriebener Schwammfilter für Garnelen Aquarium bis 200 Liter
Schwammfilter für Aquarien bis 200 Liter. Sicher für Garnelen dank feinem Filterschwamm und Luftantrieb. Eine zusätzliche Luftpumpe ist für den Betrieb dies
That's for a very small amount of water 25-30L.i think i found something better!
Looks perfekt I guess..
Sponge filters will work, but they will not be very effective until they are covered with nitrifying bacteria. Hence, you will be subject to ammonia problems. If you don't need to QT any fish immediately, put the sponge filter into the display tank or sump for a month or more and it should be able to process ammonia from the fish in QT. Biospira or some of the other bacteria in a bottle products may speed the cycling of the sponge filter.
i need to do it immediatlely.. so need to work with bacteria I guess..
Yes, be sure to test for ammonia daily. Sometimes, the Bacteria in a Bottle takes several days to become effective. If ammonia gets too high, you will need to do water changes until the bio-filtration is functional.
Usually you need to add a source of food for the bacteria to grow and populate the surfaces of the filter.
