I have no doubt the pond needed liming as it made all the difference. There seem to be a good number of BG that would give the bigger bass a meal. I'm debating now how long I should keep a bloom going. When the initial bloom wore off the visibility went to about 3.5' -4'. When I added recommended amount of perfect pond + last week the visibility dropped to about 18" (where it is now). I'm wondering if I should keep bloom going through summer or stop fertilizing.
