Cecil/Bill, I certainly don't have any issue with the 'green' water, I have found just the right amount of fertilizer and luck to keep it that way. I think Cecil is right, I am trying to fix things that are not broken. I have a good excuse though... there is not a thing I can do about my terribly diminished water level at this point in time.. so I am looking too hard to find other things I can fix. I appreciate the info lads and I will do my best to leave well enough alone. Now if only I knew how to make it rain...
