I am looking for recommendations for the best pump under $200 that is capable of throwing approx. 2000 gph. I see that the Danner Pro HY-Drive 2100 GPH Water Pump fits my requirements...does anyone have any feedback about them? I am using the pump for a homemade wet/dry on a 225-250 gallon indoor pond. One more thing...I prefer to use a external pump....not submersible. Thanks!!!
