pond pumps wich one is the best to buy

Question
looking for a submersible pond pump around 700-1000GPH wanting to buy best made longest lasting /

Answer
Hi
The first question is the pond accessible to humans? i.e without fencing
If it is the case I would not recommend a submersible pump.
But if not the best is Grundfos if it available in the area you are located.
Otherwise Haywards, Jandy or Pentair.
