Equipment for your Garden Pond
Lining a Pond
One of the most crucial aspects of pond construction is ensuring that you have enough pond lining. Having too little pond liner means you will need to rethink the size of your pond or you will have a pond that is not always watertight.
When measuring your pond you need to consider not just the length and width that you pond will take on the ground, but also the depth of the pond into the ground Meaning, you need to know the volume of the pond.
A good rule of thumb is to measure up then add a couple of feet to both measurements. This will allow your rubber pond liner to sit slightly proud of your hole in the ground ensuring that your pond is fully watertight and that your pond water does not seep away.
Pond Filtration
Another essential part of building a pond is a good filtration system. If you look for pond filtration online you should come up with a good range to select from.
What do you need from a filter system? To achieve an efficient biological surface you need to ensure the water that enters the filtration is rich in oxygen. This helps the friendly bacteria oxidise the waste products through the nitrogen cycle. This is called aerobic filtration. Filter systems must fulfil the following criteria:
- The filter volume should be 10% minimum of the ponds volume.
- The flow rate you should aim to achieve is to turn over at least half the ponds volume once per hour.
- There should be a number of chambers in the filter that when cleaning can be separated and individually emptied. You should also include a Vortex.
- The biological surface area needs to be at least one square metre per ten cubic metres of pond water.
- An ultra violet clarifier should be installed to eliminate single celled algae, which causes green water.
There are two main types of filtration. The first type of filter is called a gravity feed where water is removed from the pond via a bottom drain. It is then forced via gravity through the filter which is sited buried in the ground close to your pond so that the water level in both your filtration and pond are the same. The water is then returned to the pond via a dry sited pond pump through an outlet in the side wall of the pond below the waterline. At this stage it is important to use a venturi on the outlet to oxygenate the returned water as the biological surfaces will have depleted the oxygen during oxidisation of the waste products.
The pressurised feed filter is the 2nd main type of filtration and probably the most familiar. This involves an internal pump that handles solids at the deepest part of the pond which pumps water through a flexible pipe to the filter which is positioned above surface level. Forces of gravity allows water to return.
Water Pumps
Without a good pond pump, a water garden is at the mercy of bacteria, lack of oxygen, and the settling of dirt and debris. In circulating and oxygenating water continuouslyd a dependable pond pump can do wonders for maintaining a healthy environment and balanced ecosystem in your garden pond. Additionally, the water pump plays an important role in keeping humans and pets safe by helping to prevent unwanted insect pests from breeding and infesting the area. Find a wide range of pond pumps to fit every small pond application from good pond retailers.
