It was in a bag at the thrift store. I just saw what it was, opened it up and it was clean so I bought it. I have a feeling it will do a good job. It just feels solid. I guess time will tell.
I'm about to have an empty 20g, We'll see what rolls along for me to toy with in there. I might use it to beef up filtration and upgrade my tree frog habitat from a 10g to the 20 when the two new frogs are big enough to escape being eaten by him. 20g should be good for three little tree frogs. And if the pump dies, the other one will still be going anyway.
