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.

  • 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

  • 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

  • Fish food for ponds .. In the early days of artificial pond and fish keeping the only food available to buy was food made to feed trout and similar farmed fish. The trouble was this type of food was first of all not formulated for feeding to carp types (koi and goldfish) and the food sank to the bottom immediately. Now this sinking factor was not all that serious since carp are natural bottom feeders but fish pond owners like to see their fish eating (don't we all) so the market need for a floating form of fish food was born ... forget flaked fish food used in aquariums and mainly which is ridiculously expensive. Tetra, a German company, accepted the challenge and I believe created the first commercially available fish food stick that reliably floated. On the back of excellent technology and marketing they established a multinational market that thrives still today. http://www.practical-water-gardens.com/artfishfoodsticks.htm pond pump selection

  • 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

  • Algae influence the water quality of the pond mainly by affecting the balance among dissolved oxygen, pH, carbon dioxide and nutrients. Algae produce oxygen, remove nutrients and take up respired carbon dioxide from both the fish and the algae itself. In heavily stocked ponds, the water becomes super-saturated with carbon dioxide. During daylight hours, algae can quickly strip the carbon dioxide out of the water, and pH levels can rise above nine in a matter of hours. Fish not acclimated to such sharp shifts may initially show signs of stress. uv light specification

  • Pond pump don't stop for more than about 60 minutes because,if you keep fish, the biofilter is starved of oxygen. For this reason two smaller pond pumps are often a better choice than a single larger pond pump. The main reason for a biofilter in a pond is NOT to filter the solids out of the water. It is to purify the water by removing offending chemicals. These chemicals are actually produced by the fish themselves by virtue of their normal breathing, eating and toilet behavior. Biofilters need a continuous supply of oxygen sourced from that dissolved in circulating pond water. Beware low oxygen levels in summer. all about pond pumps

  • A waterfall adds oxygen to a pond by creating a large surface area across which air can be absorbed into the circulating water. A simple fountain also adds large amounts of oxygen to pond water. A fountain is cheaper than a waterfall. It makes good sense even in the smallest pond to have a small fountain running night and day if at all possible. When fish deaths occur in a pond they often occur in the early hours of the morning ... at this time oxygen levels tend to be at their lowest. all about ponds and waterfalls

  • 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

  • Use garden pond bottom waste on the compost heap. This organic matter is full of mainly anaerobic bacteria which will catalyze the composting process. Backflushings from the pond filter can be sprayed onto the lawn or garden as a source of nitrogen fertilizer. Use black or opaque pipes in your pond instead of transparent low cost plastic tubing. Since light cannot penetrate the black piping the algae growth inside the pipe will be very considerably reduced. This means less maintenance and also less expenditure on replacing transparent pipe when it becomes clogged with algae. submersible pumps

  • 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
