Thanks esshup,
I was hoping it would help, but it is a massive amount of water. It will still be great structure. My water levels don't fluctuate much, since it's ground water/spring feed from the bottom, I do have a little rain water run off that should be dealt with when I get some grass sown around the edges. Looks like I will be spreading ag lime for quite some time in the near future. May have to change my handle to "Big Limer". :-)
