A canister's benefits come from easy maintenance, media storage capacity and pump strength. In my opinion, your filter is too small for a 20 gallon tank. Sponge filters work excellent, but take up a lot of room.

My honest advice? Even on a budget, your life support system, whether we are talking about a filter or heater or whatnot, is the most important item you will ever purchase for your frogs, never skimp on it. Buy the best filter you can afford. Search online and you should be able to find a decent canister filter such as a fluval 205/6 or an eheim 2213 for a decent price.
