When my pond was redone in August 2015, I was not on pond boss forums, and it was only compacted using a dozer. I lose from 3/4 to one inch of water per day due to seepage. I attribute it mostly to poor compaction. I hope you don't suffer the same. I am on my second water pump now due to having to keep up with the leaks with supplemental water. It's a hassle, and not worth it long term.
