The first pond most people own is the preformed pond because it’s more easily available and easy to set up then other types of ponds. These types of ponds are found in big retailers all across the country. Preformed ponds are template shaped containers that are popular with beginners. While the shapes are not unique, they can bring you enjoyment for many years.
When picking out a pond shell, you will quickly find that most of them are constructed from polyethylene plastic material. These products, when exposed to the sun, will last several years (two is about the average figure). However, this means that you will need to replace them every couple years – something that’s expensive and time consuming.
A far better option is to look at buying a preformed pond made from fibreglass material. These shells are very sensitive to rising and shifting in the material if the pond is placed in a low lying area or heavy frost is present in the area. If you are in a colder area, it’s important to empty it to prevent the water from freezing which will damage the fibreglass preformed pond.
Aware of these issues, many of the manufactures have solved the problems by creating ponds in a box. There ponds are easily transported by folding up. They are constructed from flexible rubber material that makes it very easy to install them. Because the pond is not very flexible, it won’t crack and it is highly resistant to UV light. These preformed ponds are highly recommended for anyone who does not want to deal with the hassles of plastic or fibreglass preformed ponds.
Keep in mind that tub ponds will likely be seen a decoration to a home and won’t add any major value. Preformed ponds also only have a limited volume of water, making it more difficult to keep the water clear. One way to ensure your pond is clear is to add a UV sterilizer which will kill living things in the water – keeping mold, moss, or other organisms from growing and muddying up the water.
Many people will people start off with a box filter which contains a small pump at the bottom of the pond which will cycle the water through a smaller waterfall area near the top of the pond. These only have limited successes though and will require constant unclogging on your part every couple weeks.
For the best low maintenance solution is to get a biological filter – this will keep your pond clear for months to come.
