I have a 35 gallon pond that used to have fish it it and now is overrun by tadpoles in my backyard. The filter broke ages ago and I was tight on money so I gave them away. I now ever have a spare Penn plax cascade 600 its an internal filter I got with a tank from Craigslist. Can I use it in my pond? Its just for guppies the pond is to small for anything else really.
