Good idea on the extra sponges.
Hydro pro III sponge is rated up to 40 gallons.
Aquaclear 20 is rated at 125 GPh and with adjustable flow,,could be just about right.
Should mention that for some folks,,these are not very pleasing from aesthetic standpoint but your call.
For surface movement,(scum?) I might use the hang on the side bracket that should come with powerhead.
Might call or enquire to be sure.
Koralia makes a nice powerhead that attaches to glass via magnet, and I use one of these in planted tank for it does not take up floor space in the tank
