Bill C. Thanks for your response to my post re Fish Farms contacts in Central Ohio area. First let me thank you for sharing your expertise with this rookie. Also, I agree with your thoughts on these Farmers lack of experience with Tilapia. Thanks for volunteering your services to identify FA for test. I think at this point, I'll hold off any attempt to locate Tilapia for following reasons. On April 01 I treated pond with Cutrine Plus (Granular) & Cutrine Plus (Liquid) plus Aquashade. Today (April 27) I treated pond again with Cutrine Plus(liquid) and at this point I have no signs of any FA at all. Maybe it's too early to have any FA, I'm not sure. Another reason why I'll hold off on Tilapia is my pond is on 5 acre lot that we plan to build on this fall and I would like to be able to monitor fish & FA on a daily basis instead of every week or so as I'm doing now. Also, to wait and see what difference my treatments this year might make.Again thank you,and all the others too, for sharing your valuable knowledge with me. Just another example of how valuable Pond Boss can be.
