| I do not have a waterfall at this time... maybe in future. I have one bottom drain, one skimmer and a 3 way valve to control flow between the skimmer and bottom drain. I want to keep the pump somewhat close to the pond to prevent extra head pressure......I have at my desposal right now without making a trip to the local hardware store, 4 cubic feet of poly floating beads, (3) 55 gal drums and a box of bio ribbon, 40watt UV filter, a canister pool filter with 2" plumbing, have access to a pool bead filter...still looking for a great deal on a external pond pump. I just want to make a system with as small a foot print as possible and still capable of good water quality. I will have approx. 10-15 koi and to start with, the largest koi's will be about 12-14" long. |
