2 sponge filters or 1 larger sponge filter in 36" long tank (30g)?

Years ago when I was fishkeeping I used HOB filters and under gravel filters, so I have no experience with sponge filters.

Would you use 1 or 2 sponge filters in this tank? And if you want to recommend anything, please feel free to do so.

Thanks!
