Lining a Pond

One of the most important aspects of constructing your pond 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.

You need to consider the depth of the pond into the ground as well as the length and width In other words, you need to know the volume of the pond.

A good rule of thumb is to measure your pond and then add a couple of feet to both measurements. This allows the rubber liner to sit slightly proud of the hole in the ground which ensures your pond water does not seep away.

Pond Filtration

Another essential part of building a pond is a good filtration system. Search pond filtration online you should find a good range to choose from.

But what is it you need out of a filtration system? To achieve an efficient biological surface you must ensure that the water that enters the filtration is rich in oxygen. This helps the friendly bacteria to 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.
• You should be aiming to turn over at least half the ponds volume once per hour.
• The filter should have several chambers which can be which can be kept separate and emptied individually when cleaning. You should also include a Vortex.
• The biological surface area needs to be at the very least one square metre per ten cubic metres of pond water.
• Single celled algae cause green water; install an ultra violet clarifier to elimiate this.

There are two main types of filtration. The first type of filter is where the water is removed from the pond via a bottom drain and is called a gravity feed. Gravity then forces it 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. Because the biological surfaces will have depleted the oxygen during oxidisation of the waste products it is important at this stage to use a venturi on the outlet to oxygenate the returned water.

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. A dependable pond water pump does wonders in creating and maintaining a healthy environment and balanced ecosystem in your garden pond by circulating and oxygenating water continuously. The water pump also plays an important role in safety by helping to prevent unwanted pests from breeding and infesting the area. Find a wide range of pondpumps for any small pond application via good water garden product shops.
