Do you plan on having the fish use them in the summer or the winter? If your pond is not aerated, there's the possibility that they will be below the thermocline in the summer, where they can't be utilized by the fish during that part of the year.
Didn't really have a plan on that, I just wanted to put the others <10' but deeper than the 4-4.5' that I was able to put these with the marker pipe.
We don't have an aerator, but have a gentle sloping rip rap spillway and we're going to run our solar pump during the summer. I don't have the funds to buy one myself right now, and my FIL (who actually owns the property) doesn't want to buy one.
I have discussed with him why it would be good to have one, especially with how deep our pond is. Most of our cover was set in 6-10' of water now that the pond is full. He didn't want to mark any of it with above surface markers (which I ***ch, cried, urinated and moaned about considering I do the most fishing and some of the upside down stumps are hang up magnets).
He reluctantly agreed to let me sink this with like 2" of the pvc above water to mark.
I may consider just putting all of these that I can make 5' or less.
