Hey Algae, I'm setting up a cattle tank to keep suckers that I catch in between fishing outings and I was wondering if you know what type of filter or if there is a small pond fountain that would be good for this. I don't know if you deal with smaller ponds or not, but if you do let me know. I'd like to keep some on hand to take down to plover or bass and also to take my leftovers from up north.
