HOB for 6 gallon tank

[Mread]

I have a new 6 gallon cube tank and I'm looking for a HOB filter for it.  I have a Seachem Tidal 35 on my 20 gallon tank and love the media basket.  I'd like to put the same set up on the 6 gallon and run the flow at the lowest setting but I'm not sure if that will work.  Are there any other HOB units that will give me the same flexibility with the media basket?  I don't want to put an inside filter inside the tank because it just takes up too much space.

I have used the Aqua-Tech 5-15 on tanks as small as 5g and as large as 20Long

When I used them I ran sponge only no cartridges. They dont have a basket just an open area.

There are some pretty small nano sponges now, yes they do take up room but I have found them unobtrusive. Have a couple in my Aquatop 4.12 (only reason I have 1 is one is run by a lithium backed pump the other on a traditonal plug in- in case of power outages- would be fine with just 1)

I have the smallest Aquaclear on each of my 6 G cubes but I also run an ACO nano sponge so I can always have a filter running even with a power outage.  My air pumps are all on battery UPS so there’s always air circulation to my tanks.  My UPS will run the air pumps for about 10 hours.  A smaller air pump should run even longer.
