I wouldn't recommend any foam insulation in a pond it can breakdown into a nasty mess..

You'll notice the action by swarms of breeding minnows around your best placed pallets.. or you might see action around all of them then you know your doing it right..


I believe in catch and release. I catch then release to the grease..
