Quick Question about Skimmers

[tbaity1401]

Im looking at the eshopps psk-75 and the psk-100. The psk-75 is rater for 75-100 gallons and the psk-100 is rater for 100-150 gallons. I have a 55 gallon aquarium. Is there any reason I should go with the small skimmer instead of the larger one?

I'd opt for the larger if you can swing the price and have room for it. More margin for error.
