I'm looking to purchase a Pond BOSS Pro Bacteria Block. I estimate my oval 1 acre 16ft deep pond to be 3,534,300 gallons, and 58,905 sqft surface area (figuring 8ft average depth as the pond's banks slope rather steeply). I run a single bottom aerator placed in the middle of the pond (also have a second aerator that is currently not installed). My question is, how should I treat with the block - Place it in the middle near the aerator? Break it into smaller pieces and place around the aerator, or closer along the shorelines? Should I install the second aerator and evenly space both of them across the middle of the pond, and break the block in half for each? Thanks.
