Looks like I ruffled your feathers alittle bit KD.I think that your post are packed full of all the info. that is needed to get somebody on the right track of solving their problems and as far as I have seen you have been right on the money with your advise.The one thing that I haven't seen in the post is some of the important advise that is a big part of making the right choise when treating a pond.Like I said saftey is the #1 priority.Shan was the only one that memioned the subject the fact that I might sound like a bartender when I shot my post from the hip was ment to prove a point.If there is advise handed out and it has health risk to a person or persons then it should always be included.The fact that nobody menioned that sonar should not be applied within a quarter mile from a potable water supply is leaving out alot of information about this product.There is this type of info with every chemical that should be included before a reader goes buys it and finds that they should not use it.The chance of somebody taking some advise from a post and using it sucessfully is great but it won't be if they end up sick or worse.Just something I just had to post.Gotta go get my drivers license renewed.
