Hi I'm Jim Newman from Making Waves and we're covering the proper setup of an outdoor pond. You are easily capable of building and maintaining a koi pond yourself. Building a koi pond primarily consists of having the proper site for the pond. In this instance we have a large backyard where they took care and they located the pond within a nice large parameter of their backyard. Ponds can be made either in ground or above ground depending on exactly what your circumstances may be. For a below ground pond that consists of koi and or lily pads, I highly recommend that you dig a pond at least 4 feet in depth in the center with 2 feet along the side. The main reason being is because you do have what is typically a big problem in keeping the koi pond and that is predator control. Predators consisting of either blue herons, hawks, eagles and or raccoons. If you dig a pond that is at least 4 feet in the center, those predators are not going to be easily going into that pond and unfortunately taking your koi. In some cities however, it will require a permit to dig past 2 feet in depth. For this you want to go right ahead and consult with your city or the building department and see if any kind of permits are required for putting in the koi pond yourself. If you do not want to do this, then hire a professional and a professional will be able to direct you as to exactly what is needed for that construction. Here we have a pond that is already setup and being maintained at this time by us. This pond consists of koi, water lilies and marginal plants. The proper maintenance of a pond requires us to come out to a pond at least once a month. When we go right ahead and do the maintenance of the pond, what we are going to do is we are actually going to perform water changes, we're going to take out all debris from the pond in the way of leaf matter, any kind of fruits that might have fallen into the pond and also trim away any of the plants that are either dead or dying or leaves that are dead or dying because of the seasons. The rapid sand filter consists of sand of a grit of number 12. You can get that at any of your brick or concrete supply store and put it in the rapid sand filter. There are other filters that are commonly available for the ponds such as Aqua Ultraviolet, Ultimate II filtration which typically uses what is commonly referred to as deed filtration. This takes place of the sand media and it acts as not only a mechanical filter but also as a biological filter as well for the proper maintenance of koi. Part of the maintenance is actually going to be going right ahead and performing a backwash of the pond at least once every two weeks. The backwash of the pond basically consists on the rapid sand filter of turning the pump off, putting the filter onto backwash then turning the pump off and backwashing the filter until the water comes out clear. During the wintertime back east, or in the mid west, if it snows, the pond will want to be turned off and a deicer put in. A deicer what you're doing is you're basically poking a hole into the ice and it is maintaining that hole in the ice. It typically floats on top of the water and heats the water surrounding that hole and makes sure that no ice actually forms around or covers that hole. If it forms ice unfortunately the fish will run out of oxygen. If you have a deicer right there however, the oxygen will be able to get into the water and you'll be able to maintain it.
