Thanks gentlemen. The next month or so I have very little free time so I was trying to make good use of a weekend out there but don't want to risk hurting the fishing as we have people coming in from out of town to fish.

Follow up info- I think we'll be using "Trophy Maker" fertilizer. I can get it through my local feed store. How long to wait if we don't see an initial bloom? I keep reading that it is visibility driven but that often time you need a re-application in 2-3 weeks. I assume that means if we get a bloom, it should be within a week or so?

Bob, I'll have my water analysis back in a couple days and will send you a copy to review. (re: gatesville)

Thanks!
