I have researched on this forum for geothermal and would be interested in up dating to find out what has been installed in the past two years. Brand and type along with problems. I plan on installing two more pressure tanks on the well and I am 75 feet deep with enough water. I filled my pond with my a 3 hp pumpand the pond is about 3 acres . I ran the pump wide open until the pond was full , it is approximately 10 foot deep or more in certain areas. Since I am almost complete with the hurricane damage I will be able to give this more thought. thanks
