Looks very.. bleh... Scrub off that algae.
That sponge filter is too big for that small of a tank, a HOB would be best.
That plant is getting sucked up like crazy also, I would do a HOB filter,
Scatter the rocks out a bit, put the small plants around the rocks, and the big ones opposite side of the inlet for the HOB filter.
I am saying that it looks huge, and takes up too much room in such a small tank. I am sure its rated for bigger tanks. Just saying.. its size.. if they OP is going for a nice aquascape, he would be better off with a HOB.actually that sponge filter is just fine for that tank..
