Wow! very cool I guess I did not realize that! I will be starting a feeding program this spring for my CNB so that would fit right in! Thanks guys I will look a little deeper into this now! I have no problem replacing my LMB with HSB if they will work. I guess I just mis understood. My pond is right at 1 acre and I am about 6 or so hours farther North of Texas so I may be prime for this!
