Pond skimmer, wrong size pump?
I had a pond built last month. I fear the pump is too powerful. The size is 6 ft by 9 ft depth from 18 in to 36 in at deepest. The skimmer states for pump up to 1800 gph. The pump installed in the skimmer is 2400 gph. It seem like the skimmer water level is too low and funny, almost whirlpool sounds come from skimmer. Is this due to the pump being too strong. Is it harmful to have too strong of a pump?
Your pump is not too big. Your skimmer is too small. You can just put the pump in the pond and direct the water over the waterfall. That will do until or if you wish to replace the skimmer.
Frankly, you probably do not need a skimmer at all. Most people do not unless they are under a tree. The person who installed your pond needs to learn how to install one properly. It is still under warranty, so call him back and insist he do it right.
