This pond was a pleasure to build. We were hired by a widow to rebuild her husband’s koi pond. The original pond was in severe disrepair and had an inadequate filtration system. The new pond features a bottom drain, Aqua Ultima Filter, 75 Watt UV sterilizer, and an Atlantic Water Gardens Big Bahama contractor grade pond skimmer filter. The pond measures 10′ x 13′ and 4′ deep. The customer wanted a floating fountain as well. We have yet to find one that works well for smaller koi ponds, so, we used a Laguna floating plant basket and a magnetic pump.
