I went in to a shop that sells/builds ponds and equipment and told them I was building a pond and would like to filter it for as cheap as possible. They told me to set up a skimmer and pump it to a waterfall filter with a 2000gph pump and that's all I would need. I told him all the sizes and that I was keeping aro, stingray ect. I don't see anyone else doing this, I see people pumping water to a diy trickle. They gave me a quote of 1500 bucks after tax for everything including pond liner, I'll I would need is the wood to actually build the pond. I did some looking around and I can buy all the same stuff from various stores for cheaper (hardware store sells the liner 100 bucks cheaper) big als sells the skimmer/pump and waterfall filter a lot cheaper too. I'm just wondering, is this a good way to go or should unjust get a pump and make a trickle like everyone else? If I buy all the supplies for the skimmer/waterfall idea I can get it between 500-600 dollars. What do you guys (and girls) think?
