Tetra have been innovators in the world of aquatics for over 60 years, and Ellie Goodall has been reading a research survey they have recently published proving that keeping a pet is good for your children.
Waterfalls or watercourses not only look great and bring the tranquil sound of running water into your garden but Andy Hobson explains that they are also very beneficial for your pond.
There are some very good reasons for adding a waterfall to your pond. Water, breaking the surface of a pond adds vital oxygen, this is not only beneficial for ponds with fish or other aquatic life but it has also been found to be very good at promoting friendly bacteria levels. This bacteria then breaks down sludge and silt which sits at the bottom of your pond and can pollute the water over time.
The trickiest part for most people is how much water flow is required. It’s actually very simple to calculate as I will explain.
First you need to measure the head height or head measurement, this is the height of the waterfall from the surface of the water, and then next measure the width of the waterfall.
If you want to achieve the type of effect that you see in most people's gardens, then the easiest way to calculate the flow is to measure the width in cm and multiply that number by 1.5, this will then give you the required flow rate in litres per minute (multiplying this amount by 60 will give you litres per hour).
It's important to have the correct flow rate as too little will just give you an unimpressive slow trickle of water, while too much will create an inappropriate torrent.
Below is an example of how to work out the flow required in litres per hour:
If your waterfall is 65cm wide: 65 x 1.5 = 97.5 litres per minute x 60 = 5850 litres per hour flow required.
If you wanted something slightly stronger then just double that number, but we would advise taller walls to your waterfall to prevent water loss.
Of course if you plan to have a tallish waterfall you will still require the same litres per hour but may need a quite large pump that can pump that height at the required rate. This is because as you increase the pumping height the output of the pump in litres per hour decreases.
When possible, always use a solids handling pump as these can pump through a much larger pipe giving you less loss of pressure and a more consistent waterfall. Try to limit the joints and fittings you use as this can cause a loss of flow.
If you are planning to have a massive waterfall or something with a very big drop it is advisable to speak with a pond specialist as they will be able to calculate an exact specification for you.

Create a Halloween party in your house or garden with ideas and suggestions from David Coton that will keep your children and neighbours thrilled and spooked on the 31st October.
Looking for some advice on how to decorate your garden for halloween? David Coton has some great ideas to help you create a horror themed garden to scare your neighbours and any trick & treaters who come to your door.
Used originally to frighten away evil spirits, now placed near the front door to deter trick or treaters, carved pumpkins have been part of Halloween for a very long time. Here Martyn Loach explains the process of creating the scariest pumpkin in your street.
To grow the biggest, scariest pumpkin in time for Halloween isn't easy as they take some time to mature and prefer a warm climate. To have the best chance of success Martyn Loach recommends sowing seed indoors during April and then planting out in late May or June.
