Good thing you have those grandkids splashing around in your pond ... to disrupt the summer water stratification.
Very true! The old fat man displaces a lot of water but doesn’t stir it up much. Until one of my cross piranha/RES makes his presence known to me. Agh!!!
12 yr old pond, 1 ac, 15' deep. RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs) I think that's about all I should put in my little pond. Otter attack in 2023.
