Pond Boss Forums POND CONSTRUCTION Creating habitat Sink hollow log help

I tried looking back at threads, but I have a pond that is about full, and I have a hollowed out tree....big enough for large bass to swim through.

Would like to add this in the pond, hopefully to give the big pass a place to hang out....but how do I sink it?

Tree trunk is 8-10 feet long and hollow part is 20 inches in diameter. I can upload a picture tomorrow.

Or am I just wasting my time on this structure. Not worried about tannins, tree had been dead for sometime, no bark, was not oak and I’m already treating pond with muck pellets and activated charcoal because of the leaves falling in.

Not sure why the photos are turned sideways.
