Given the info you posted i think it's just under for that size tank. Ideally you want a filter with a capacity around 4x your tank. Your tank is about 85L, but the filter is recommended for up to 50L.
Might be ok if you stocked very lightly, but not for stocking at full capacity of your tank.
In your tank dimensions you wrote 2 12 for the height. Is this an error?
