I added a Vertex Air 1 plus to my pond early this week from Ted Lea (who was very helpful, BTW) and am contemplating how effective the tilapia will be given the lower water temps in the upper layer of the pond now. Last week, surface temps were in the low 80s which is perfect for the tilapia. Since aeration was added it's now in the low 70s. Does anyone have any experiences for comparison? Maybe the aeration benefits counteract the tilapia's slightly lower metabolism? I don't have a source for the tilapia yet but I'm working on it.
