Having a pond may decrease the value of your home. MYTH
Ponds can be a great addition to your home that might even pay dividents. You should be able to recoup 150%-200% of what you put into a water feature such as a pond. Ponds have a universal appeal, unlike pools.*
You cannot have a pond in an area where there are a lot of trees. MYTH
Yes, you will have more leaves in your pond in the fall but, by the same token, the shade provide by the trees will help minimize the algae bloom in the summer. Furthermore, if you have a skimmer sucking the top quarter inch of water off the top of your pond, it will pull most of the leaves and related debris into an awaiting net. This takes about 30 seconds to empty.
The presence of rocks and gravel make it difficult to clean your pond. MYTH
Rocks and gravel offer a natural place for aerobic bacteria to colonize and set up housekeeping. This bacteria breaks down the fish waste and debris that would otherwise accumulate in the pond and turn into sludge. Regardless of your pond’s location (i.e. close to trees and loads of leaves), or how many fish you have in it, you’ll find that having rocks and gravel in your pond not only makes it look better, but it makes it healthier as well. So contrary to the myth, having rocks and gravel on the bottom of your pond actually allows Mother Nature to clean up after herself.
You have to bring your fish inside for the winter. MYTH
Fish do fine during the coldest of winters as long as you give them two feet of water to swim in, oxygenate the water, and keep a hole in the ice with a bubbler, allowing the naturall produced gases to escape from under the ice. The fish will spend the entire winter hibernating at the bottom of the pond and then they will slowly wake up as the water warms in the spring
Your pond must be at least three feet deep in order to keep koi. MYTH
There are thousands of two-foot deep ponds around the country, full of happy and healthy koi. The water in a two-foot deep pond will generally only freeze eight inches down, even in the coldest of climates, because of the insulating qualities of the earth that surrounds the pond.
A pond in your backyard means you will have a lot of mosquitoes. MYTH
Mosquitoes will generally only lay their eggs in still, stagnant water. If the mosquitoes happen to lay eggs in your pond and the mosquito larvae hatch, the fish in your pond will consider them a treat and will pick them off the water's surface with great enthusiasm. Your skimmer will sweep up whatever the fish miss. Another option is to use a natural mosquito larvae killer.
I have liabilities or safety concerns. MYTH
It's natural to have these thoughts and concerns, but it is important to remember that a professionally-installed water garden has steps leading into the pond. The first shelf is only ankle high once the gravel is laid down. The next shelf is up to your knee, while the smallest area in the bottom is just above your knee, so it is not constructed like a swimming pool. We do recommend that you make your neighbors aware of the water garden and educate your own children and friends about the safety of any body of water.
