I think your return policy needs a lot to be desired. I tried to return it but you would not accept it because you said it was used. I installed it but only let it run for about ten minutes and decided that it wasn't going to work for me. The waterfall flow was not what I expected. How is someone supposed to know how it will perform without installing it first. I will definitely not purchase any more items from your store if this is how you treat your customers. Any of the big box stores like Home Depot or Lowes will accept returns with no questions asked. My pump is a 1200 gph and that waterfall should have worked but the waterfall was not very forceful. So now I'm out $150. Thank you for your great service and quality product.
