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.

  • 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

  • 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

  • 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

  • Oygenators, pond plants ...The best by far for the pool or pond. is also often referred to as "Curly Pond Weed" but is most rightly called aragasiphon major or more commonly Elodea crispa (South African native). This has a tendency to take advantage of highly nutritious pond environments by filling them up, but at least you don't get algae. It is easy to control by just snapping handfuls of it near to the source of growth. Fish love to spawn on or near it and it is dense enough to provide protection for the eggs and the subsequent fry. For indigenous plants to the UK: Water Starwort, (Callatriche stagnalis), rampant but easy to crop to its source. marginal pond plants

  • I received a very interesting question this week. The question was what is difference between a biofilter and the powder she throws into her pond every week as recommended by a dealer. The powder she was referring to is called a bio-starter or bacteria starter. These powder products are offered by many companies and are probably worthless in practice. The powder is supposed to be a mixture of naturally occurring bacteria that are also found in biofilters. The types of bacteria required for effective biofiltration convert ammonia to nitrites and then to nitrates. All fish ponds need a biofilter. This is non-negotiable. pond biofilters

  • Thinking about a pond? ... The pool must be in full sun especially in the UK. Away from trees and prevailing winds that could carry leaves into the pool. Avoid trees with poisonous leaves. In the UK these include Willow, Elder, Poplars, Laburnum, Yew and Oak. Avoid too much exposure to prevailing winds. Avoid boggy areas ii your landscaping ideas. Consider now whether you will have waterfalls, fountains, filters, lights and other accessories like Ultra Violet Clarifiers. You will need an adequate power supply and the connections to cope. Consider accessibility to a water supply. What are you going to do with the excavated soil? Keep the top soil, but what about the rest. fiberglass water features

  • 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

  • Many people use salt in their ponds. I do not recommend it but the reason is to help prevent parasitic diseases that lead to complicated bacterial diseases. It is important not to overdose and if the intent is to remove parasites from individual fish then rather place the fish in another small temporary pond loaded with salt for a few minutes. Use about 2 lbs per 20 US gallons of pond water as a general treatment. As a short term soaking to treat individual fish use about 3 times as much salt as above. Adding pond start bacterial mixtures can do no harm especially at springtime. blanketweed in fish ponds

  • 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
