If you are looking for pond pumps or filters, don't go to Lowes. My 2 month old SMARTPOND 2,00 gph filter with UV has started to get distorted and will no longer sit flat on the ground. The filters are too fine, clog quickly and are a pain to remove, clean and replace. The pads are also NOT available from Lowes or Smartpond (They have not returned my calls or emails) The O-ring is problematic and the clips securing the top are cheap and flimsy. I bought the mate to the filter as a pump. The 2,000 gph Smartpond pump. It is working well, but now that I am able to read the reviews online, apparently the pumps never last more than 14 months. Right out of warranty.
