My husband and I just moved into a house with a 3/4 acre pond with a fountain. Our fountain's water pump (cal T4000) died 2 weeks ago. Our fountain is a floating fountain and it was anchored by the pump. My husband just purchased the Aquasurge 5000 which seems super heavy and states it is not to be placed directly in the pond. Can we use this one anyway or is there another one out there that we could attach our fountain to and that can float in our pond??? We are pond idiots. Thank you!
