The gypsum is working in catfish pond! Yesterday caught 10#+ on a "Little Cleo" 3/8 oz spoon. I have ordered some pellets (gypsum) to try, rather than powder we have used. Have never had a bloom in this pond. If we can achieve 10-12" clearity I want to add some cottonseed meal. The FA aspect may be covered with the dozen or so talapia feeding with cats? Am also wanting to sample fish BGs. I have no ideal whats survived! Funny thing is you worry at 12" and we just want 12" visibility.
Thanks as always for the reply!
