Sufficient filtration for 90g?

[thekarens]

Right now I'm running an Eheim 2217 and a sponge filter (can't remember the name) that's rated for up to 125g. Is this enough filtration or should I add the second sponge filter I bought? Right now my tank has 20 cardinals, 4 rams and a horseface loach. I will be adding some juvie discus from Dan at Gulf Coast here in the near future.
