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.

  • 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

  • To correct pH problems in a pond use dilute solutions of vinegar, or lemon juice for high pH readings and baking powder for low pH readings. Make sure you do not add too much at once. The procedure is add some, wait, test again. It is important to always test at the same time every day since the natural pond cycle creates pH changes at different times of day. For example as carbon dioxide is released by plants the pH may well decrease, When the plants absorb carbon dioxide the pH could rise again. About 10am is a good time to test. all about water garden fountains

  • Bio filter starter bacteria ... Think carefully before buying any so called bacteria starter or bio starter. In general do not add anything to a pond unless you understand why you are doing it and are sure of the benefit to be gained. If no obvious, proven, financial or fish health benefit then Do Not Add to your pond. Many commercial pond products are a total waste of money and time. It is because many people do not have biofilters that products have been "invented" to compensate for this inadequacy. Manufacturers are quick to see opportunities to add to their turnover. biomedia for pond filters

  • 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 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

  • Oxygen in ponds ... On occasions fish in ponds with no fountains or waterfalls may look listless in winter due to carbon dioxide levels being excessive but the problem quickly sorts itself out when windy and bright weather returns. In summer water can hold much less oxygen and the animal and plant life (algae) is also thriving due to higher temperatures along with more nutrients in the water associated with feeding fish. The living organisms are therefore emitting more carbon dioxide in a situation of potentially disastrously low oxygen levels . Fish may then die from suffocation. uv maintenance, lamp changes

  • Must the UV be placed before the biofilter? In theory it does not matter at all but in practice if you have a simple box type filter is must be before the filter. Reasons are: The UV works under small pressure - water must be forced through it while the biofilter drains under gravity. In sand filter systems (which I do NOT recommend) the UV light comes after the pond filter because the whole system is under pressure. Not applicable in many cases but you can also split the flow from your pond pump - part through UV light and part through biofilter. all about pond uv and algae

  • If you pond is losing water then do a quick check by shutting down the pump. If the level stops falling then the leak is outside the pond itself. If the level continues to fall then obviously the leak is inside the pond itself. When a constant level is reached then you know the leak is at that point where the surface remains level. Leaks from concrete ponds are notoriously difficult to repair and many sealants claim to do the job. In my experience fiberglass resins with glass fiber are best suited and it is worthwhile doing complete resurfacing job. sump pumps

  • It is a good idea to pump out about 10% of your pond water every month or even weekly if you have lots of fish and replenish with tap water. The reason is that nitrate levels slowly build up and can reach a level that is too high for the fish in the pond to tolerate easily. The easiest way to arrange this is to place a valve and "Y" or "T" piece into the pump line then all you need to do is connect a temporary pipe to the valve and lead the pipe to a spot in your garden - pond water makes for a good garden fertilizer. fiberglass water features

  • Biofilters and bacteria starters ... Some manufacturers claim that their bio starters contain Nitrosomonas and Nitrobacter. Now it is extremely diffiult to freeze dry and keep alive such sensitive bacteria so any claim should be backed up by definitive proof of the fact that such powders do contain those bacteria and they are in a form that will work. If there was a viable population when packed then the question to be asked is are the bacteria still viable ater "x" weeks on a shelf in non-controlled conditions. If the concoction does not contain Nitrosomonas and Nitrobacter then what value is it anyway? biological pond filters
