Sorry for confusion, did not meant it was for you, just that it is the king of all canisters. Concur the Fluval's 406 is more appropriate. What I would do is estimate the actual volume of water in the tank; and then get a filter that flows that volume at least a few times per hour. So if a filter is rated for a 100 gallon tank and you have it filled 1/4 of the way (or less) it would be over filtering your tank 4 or more times the rated output, which is good for a high bio-load from a Pixie .
