Ponds in winter ... Something very strange happens to water at 4C (39F). Instead of warmer less dense water being at the surface, as in the summer, the density changes and the water that is closest to freezing becomes the least dense and floats to the top. The result is that the bottom stays at a fairly steady temperature under a blanket of cold or frozen water. If the pool freezes, there is nothing to worry about for a few days. There is plenty of oxygen in cold water even if the fish needed it. But if there is any rotting matter in the bottom of the pool, toxic gases produced in the muck could build up. In order to maintain gaseous exchange between the water and the air, float a ball or a piece of wood in the pool. all about ponds and waterfalls

The pond filter as winter approaches ... if you have not looked already the filter is in need of a major service. The Ultra Violet clarifier needs cleaning too if you have one. The filter needs back flushing if you have that facility, otherwise scoop out the medium and rinse it in pond water or rainwater to flush out the worst of the muck. It does not need to be spotlessly clean, but check the chamber in the base because if the system has been overloaded at some time in the summer the evidence will be there to see. Scoop out this mess and rinse with pond or rainwater water. water gardens and pond filters

Normal centrifugal pumps can operate against a closed valve with little effect upon the well-being of the pump. What you should not do however is restrict the suction side to control flow unless this is for a smallish fountain pump. You know when a pump suctions needs cleaning when the height of your fountain or flow down the waterfall reduces significantly. These days the best pumps do not have sponges inside the suction body. Such sponges are a source of major hassles especially in summer when they block up every couple of days and have to be removed. submersible pumps

Water has a maximum density at 4 degrees centigrade, about 39 degrees Fahrenheit so when a pond has a frozen surface the water at the bottom of the pond is normally at this temperature (higher density water sinks). Only in extremes of climate or in very shallow ponds therefore does a pond completely freeze solid. As the ice gets thicker form the top downwards then the water becomes even more insulated and will tend to stick at 4 degrees or 39 Fahrenheit. pond pump flow rates

Koi and breeding fish in ponds ... Two key factors that stimulate koi to breed are water temperature and day length (photoperiod). These stimuli work in tandem to influence when koi spawn. Water temperature will fluctuate at comparable dates from year to year, whereas photoperiod is far more consistent. I.e. We know that June the 21st will be the longest day each year but that temperature will fluctuate year on year and is not as predictable as day length (especially up in Lancashire!). The overall effect of these interactions means that koi will spawn at different times all over the country (or perhaps not spawn at all). http://www.practical-water-gardens.com/longkoispawning.htm water gardening and water features

Once upon a time all ponds were concrete. Today unless you wish to have a very large or special pond concrete is NOT the material to use. It is simpler, cheaper, better and quicker to use pre-formed ponds ideally made from fibreglass in natural rock finishes with matching waterfalls or streams. If you want a pond whose volume is larger than about 500 litres then it is best and most economical to use a black plastic liner designed specifically for pond building all about ponds and waterfalls

If you want to ensure your pond always stays crystal clear then an ultraviolet light must also be installed since without this the risk of a pea-soup coloured water developing is great. Fish and biofilter bacteria need large amounts of oxygen to survive so a reliable pond pump which will operate 24 hours per day every day must be obtained. A biofilter even the very best (vortex type biofilters are the best but are difficult to install and are only necessary on large sophisticated koi ponds) koi filters

Lighting in and around ponds creates a brand new dimension and attraction to the garden. Normally for safety reasons these are low voltage. Lights can be submerged or above the water surface to create immediate impact and variation. You have submerged colored lights normally pointing up to the surface of the water. These could also be plain white light of course. Others focus the light down onto the bottom of the pond by creating a mushroom or umbrella effect. Still others float around the surface encased in glass globes. koi ponds and koi fish

Measuring pond volume using science .. this is worth pointing out for its simple but brilliant bit of chemistry. Once more I am grateful to a reader for pointing this out to me. This method depends upon a pondkeeper using salt in the pond water. By measuring the salt concentration in the pond water before and after adding a known amount (lbs) of salt to the pond it is possible to calculate the pond volume very accurately and easily assuming the salt hydrometer is also accurate.

pond pump is not kinked
Must the UV be placed before the
biofilter?
A waterfall adds oxygen to a pond by
creating a large surface area
Submersible pond pumps can operate
against a closed valve
It is a good idea to pump out about 10%
of your pond water

can eat
