I have around 60 3 hole cinder blocks I am planning on using a structure in a 1 acre pond. I have seen pictures of round cinder block reefs and also seen some people scatter small piles of random cinder blocks.
What will work better, 2 cinder block reefs or more smaller piles of cinder blocks.
I don't have a ton of structure currently and am limiting it to one side of the pond. Other side will stay clear for swimming. I have a few x-mas trees to put in and have half a dozen of the fish hiding pvc structures in currently. Other than that, I don't think t here is much else out there in the pond.
