Equipment

Filters are designed to specifically help create healthy water quality in your pond.

Pond filters can be housed outside or inside the pond depending on the style of pond and space available. Filters require a pump to circulate pond water through the media (in-pond filters often have a built in pump). There are a variety of creative ways to disguise external filters like creating waterfalls or well-designed planting. A pond filter contains a specific high surface area biological media which make the ideal home for the bacteria which carry out the nitrogen cycle.

The water is circulated through the biological media and supplies the bacteria with a steady supply of waste chemicals and the oxygen they need to process them. Filters will also have media to remove visible waste (mechanical filtration) to keep the pond water clear.

The other thing to remember is that ponds are an open environment meaning they can be polluted by outside sources like: run off from heavy rain, garden chemicals, detergents, concrete etc. It is important to be aware of possible pollutants as they can change the quality of the water and make it unhealthy for fish and wildlife.

The addition of a pump aids the biological balance of the pond by introducing oxygen stopping it becoming stagnant and smelly. Pumps are often used to create fountains and water falls which circulate water and break up the surface of the water, adding oxygen.

To ensure the correct level of circulation (moving water from the bottom of the pond to the surface) your pump should have a flow rate (described in lt/hr) of half the pond’s volume per hour e.g. 1000litre volume pond = 500lt/hr pump circulation.

This will not be sufficient for an ornamental fish pond where the population of fish are sustained by feeding.

The main way oxygen will enter the pond is via the water’s surface. Any agitation of the surface will cause oxygen to enter the water. Therefore, if oxygen levels are low, fish will tend to swim closer to the ponds surface where oxygen levels are highest. This also means that any movement created by pumps, filtration systems, water falls or fountains will add oxygen. Many pond keepers believe that an air pump adds oxygen because of the bubbles it creates, when in fact it’s the circulation and water movement it creates that really adds the most oxygen. Encouraging any surface movement will ensure your pond’s oxygen levels is refreshed throughout the day.

Oxygen levels are also lowest in the warmest times of the year as the level of oxygen in water lessens the warmer the water is. Water will evaporate from the pond in warmer climates, less water trying to support the same amount of pond life results in low oxygen levels.

The Powersafe range of switch boxes have been specifically designed to protect your equipment from failure.

Each individual double pole switch gives total electrical isolations when switched off. The unique power indication system lets you view the power status at a glance, power on, power on stand-by and power failure due to a blown fuse.

There are individual fuses for each switch that provides overload protection, if one fails, other equipment is still able to function
