get an aerator; it takes much of the pucker factor away. I keep a bloom, but not always 12-18 inches due to water loss in summer. I feed pretty regularly, until one of my cheap feeders clogs or the coons somehow get to it and destroy/or submerge it.
In ponds an acre or under I think you need a combination of feeding, monitoring alk. and bloom depth, aggressiveness of fish at feeder etc. to get things right. I am afraid that too heavy of bloom, especialy if you have cover, will just perpetuate too many small BG. I like the saucer BGs. Right now, I havae 3 species which all frequent the feeder, I like it that way, the lower water has also caused weeds and some cover to be dry.
Problem is, I now have fish that turn their nose up at worms at times. Need to order Stubby Steves(or make a panty hose pellet fly).
