It's more difficult to create a proper ecological balance in a small pond, which can lead to poor water quality.The smaller size can have repercussions later including: The main disadvantage is that preformed ponds are usually quite small and shallow compared to custom-built liner ponds. If sufficiently powerful, a pump can be employed to operate a waterfall or fountain in addition to supplying the filtration system.There are however some disadvantages to preformed plastic ponds over traditional liners, or other types of preformed options. Pumps that are used for passing water through a filtration system should be robust enough not to become choked by debris from the pond.
Typical pond setupĪ typical pond setup uses a submersible pump to supply an external filter by the waterside. To make sure ammonia does not build up to dangerous levels, add zeolite – a compound that removes ammonia from water to the filter. In a new pond, it will take time for beneficial bacteria to develop in the filter. When cleaning a pond filter, always wash the media in dechlorinated or pond water, to safeguard the bacterial population. Check the filter flow rate and water quality regularly any drop suggests that the filter needs cleaning.

Having passed through the media, the clean water then returns to the pond via the outflow or can be run through a further series of filters to maximize the water quality. The bacteria break down ammonia produced by the fish, as well as other waste matter. These can include brushes or layers of filter foam of different grades that sieve particulate matter from the water and also serve as biological filtration media, on which beneficial bacteria can grow. Water from the pond is passed through an internal or external filter unit that contains layers of filtration media. Pond filtration systems work on the same principles as aquarium filters, albeit on a much larger scale. Most pumps are equipped with a pre-filter – ranging from sieve-type fixtures to foam-sponge attachments – which helps to prevent debris in the pond from entering the pump unit and causing a blockage. All designs of pumps, from submersible units to more powerful surface models, work on a similar principle: an electric motor draws water through the unit and expels it through an outlet. The pump is a critical component of a filtration system, providing the power to force the water through the filter unit. Butyl rubber is probably the best material to choose, partly because it is very elastic and so will not crease as much during installation as other materials.
Less expensive liners, such as polyethylene, may not last as long as higher quality flexible liners, such as PVC and butyl rubber, which are more resistant to attack by the ultraviolet component of sunlight. What is the best material for a pond liner?Ī wide range of flexible liners and preformed pond units are available to suit most budgets, but it can be a false economy to purchase the cheapest option.

Large concrete ponds, by contrast, are considerably more expensive, and may even require the services of a professional installer. Creating a pond using a Galvanized tank or a flexible pond liner or installing a preformed pond unit does not require advanced construction skills and can be relatively inexpensive. The availability of modern pond construction materials provides a wide choice for the hobbyist. Construction choices Flexible pond liner or preformed?
