How To Use These Links

We have extracted brief information about the page you will go to if you click the link at the end of each paragraph.

  • Pumps and maintenance ... more and more modern pumps are being sold without sponges to reduce the hassle of sponge cleaning. Do get one of these in preference to one with a sponge if you like the idea of less maintenance. This type of pump is generally more robust and can handle small solids going into it without breaking the shaft or rotor. fountain pumps

  • If you have very young fish in danger of being eaten by larger fish you can seperate them until they are a bit bigger as follows ....... Create a fine mesh bag about 2 feet deep. Attach the bag to pieces of foam (or maybe polystyrene) that float creating a ring or square. Add a bit of weight to bottom of net ... eg stones and let it float around the pond. Of course you must catch the fish first and then put them in their safe floating environment. backyard ponds

  • 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

  • Ponds & algae concerns ... At night, both algae and fish consume oxygen from and exhale carbon dioxide into the system. Algae compete with the fish for available oxygen in the water. A potentially serious impact of an algae bloom is the risk of an "algae crash" triggered by temperature or barometric pressure. When an algae bloom collapses, dead algae cells settle to the bottom of the pond, adding to the decomposing sediments oxygen demand. As the dead algae cells rupture, they release organic nitrogen and phosphorous back into the water, adding to the systems nutrient load. pond algae

  • Sponges in pond pumps ... 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. So long as you keep this type of pump away from heavy debris on bottom of pond (stand the pump on a brick for example) you will get away with removing the sponge permanently ... although such use would nullify the pump's guarantee. The sponge is there to protect the impellor form debris damage. fountain pumps

  • Ponds & Springtime ... Apart from maintenance problems, the main thing is the blanket weed, spirogya, cotton weed whatever. It is the candyfloss type of algae that gets a start on the rest of the plantlife in the pool and just loves that bright sunlight. It also loves water with a high pH. So if you reduce that with proprietary chemicals, although I have a client experimenting with vinegar, you will find that any other treatments are a lot more effective. Most aquatic suppliers have some remedy. Barley straw is effective for certain periods as long as the water is very well oxygenated and the straw is changed at regular intervals of not more than 10weeks water gardens, pond keeping

  • The job of the biofilter is to purify the water first and foremost. Fish excrete ammonia which if allowed to build up results in the fish poisoning themselves ..... remember those goldfish in the bowl which lasted about a week ... they died because there was no biofilter to purify the water. The fish poisoned themselves to death in simple terms. It is easy to make a homemede biofilter for yoru pond. pond filters

  • If you are sick and tired of looking at debris on the bottom of your pond then consider buying an electrically operated vacuum cleaner. Just make sure that it is safe for pond use. OASE make the one that is best known. The latest version is Pondovac 2. For people who do not like to get their hand too mucky when cleaning out a pond there are specially made long length gloves extending right to the shoulder. If the water is a little too cold then the fishermen amongst you could easily use those waders to enter the water if cleaning has to be done. fountain pumps

  • To determine an approximate average depth of your gold fish or koi pond whose depth is not constant take a stick and mark it in intervals of say 3 inches with an indelible ink pen. At 10 different places in the pond insert the stick and record the depths (10 numbers). Add the numbers together and divide by 10. Use this answer as the average depth of the pond. If your pond is of equal depth and the same cross section then you can very accurately measure the pond volume. solar pumps for ponds

  • 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

 

Never switch off your pond pump for more than about 60 minutes

Make sure the delivery pipe from the 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

Lighting in and around ponds creates a brand new dimension

Do not feed more food than what you fish can eat
