I did some digging. UV sterilizers kill any free floating bacteria, algae, and parasites. Several of the diseases these frogs are subject to are at one point free floating. Several are not. I am going to run it on the lowest setting. Other than the fact that I can see it in the tank and it will be an additional piece of equipment to maintain there is no real drawback to it. We plan on moving in the spring to a larger place. My tank sits in a built in cubby right now in our spare bedroom. Once we move I am going to get a stand for it and a canister type filter. There is one I am considering that has a built in UV and I will also thrown on an in-line heater to keep all of the equipment out of the tank.
