I'm sure there is something obvious I am missing. I'm thinking about getting my 7' pond dug out deeper - 15 to 18 feet so that I can sustain trout over the winter and summer.
I've been told that a diffuser is a bad idea as it will de stratify cold water at the bottom which trout need and I should have gotten a fountain but I saw a recommendation somewhere that diffuser can be suspended at half height in the summer.
How does one do this? Won't it just sink. Should I attach a mooring rope to the other end of it opp side from the airline and attach it to the bank. Then pull in the rope in the summer. Perhaps a mooring rope on both ends to prevent damage to the airline ?
