"Spring" into your pond!

"Spring" into your pond!

Finally winter is over!
Now the weather is warming up it is a good idea to venture out into the sunshine and see how your pond is going.
Inspecting and cleaning your pumps and filters should be done now so your pond is ready for the coming warmer weather in summer, if your UVC globe is older than 12 months, now is a good time to replace it as although it still works, after 12 months they lose their efficiency and will no longer be effective in controlling green water algae. 
Pond plants that are now too large for their pots can be divided and potted and any dead lily bulbs can be removed and discarded. Leaves blown in from winter storms should also be removed and any excess fish that have appeared over summer and are now larger in size can be given to family and friends or sold to pay for fish food etc!
The Oase Pondovac 4 is a convenient way to vacuum unsightly silt, sludge and leaves from the bottom of your pond. Thanks to the patented twin chamber system, it is possible to vacuum continuously without interruption. 4 useful nozzles are provided to clean into every corner of the pond. A powerful 1700 watt motor allows even deep water to be cleaned successfully with a maximum suction depth of 2.4 metres.  
The Pondovac 5 has just been released into Australia and features the ability to pump waste water over height differentials, a suction depth of 2.5 metres and a maximum flow rate of 8000 l/hr.
Normally, waste water is simply discharged onto the garden and is an excellent organic fertiliser, especially good on flower beds. If removing larger particles from the pond, use the mesh bag to catch the particles and recycle the water. The Pondovac 4 and Pondovac 5 are also excellent for removing residual silt from the bottom of filter systems.  
There is also a smaller version of the Pondovac 4 called a Pondovac Classic; this vacuum can be used as a wet and dry vacuum for the pond and household and features a 1400 watt motor with a suction depth of 2 metres and it also features a 27 litre storage wastewater tank with an automatic activation and emptying through clever motor control. This vacuum is ideal for the home pond gardener and comes complete with hoses, attachments and filter bags. 

As the weather begins to get warmer as summer approaches you may notice your fish begin to swim around a lot more and chase each other, this is how goldfish and koi breed! 
Male fish will begin to pursue the females around the pond and eggs will be laid and fertilised on pond weeds and generally scattered around the pond. 
Goldfish males develop small white lumps on their gills and head, these are called "breeding tubercles" and only appear during breeding season, koi, however, can be sexed all year round by their fins, males have pointier pectoral fins, while a females pectoral fins are more rounded. Butterfly koi are a bit more difficult to sex due to their long fins on both males and females!
