I shut my bog down for the winter and within 2 days the water was gone! I knew I had a leak somewhere in the pond causing about a 2-3" water loss every couple of days. It looks like the leak is on the bottom of the bog as the cleanout pipe I have shows almost no water. Can I leave it shut down for the winter or will my plants all die? I have a collection of Louisiana and Japanese iris I just put in. Most of the other plants were pulled. I can leave it running but I'm concerned about hose from pump and spillway freezing up. Just redid this bog 2 years ago!
