Get as many dead fish out as you can. More will probably float up tomorrow, and the next day, and the next....
I'm not knowledgeable when it comes to aeration issues, but I've seen my share of bad water. I think since you're in Texas you need a serious game plan for 2008, and just try to get through the next few weeks. I don't know if there's a magic bullet for you. Do you expect enough runoff over the next couple of months to replace your water?
