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

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

A pond is not just a hole in the ground you casually dig one day, fill with water and then hope it will add value to your life. Without care and knowledge that hole in the ground will cost an arm and a leg and will not please you. In fact it will become a nightmare. Unless you go out of your way to learn the really important parts of pond keeping then do not even dig the hole......... it will not be worth it. fiberglass water features

Pumps ... most small submersible pumps have impellors designed to turn in a single direction. This type normally have curved rotor blades for improved pumping efficiency. To make sure they do not start up in the wrong direction when you switch them on this type of rotor can only be turned by hand about 3/4 of a turn before it comes to a deliberate stop. If and when your pump suddenly stops pumping this is the first and easiest test to do to find out if the rotor needs changing or if something more serious is wrong with your pump. If the blades go round and round and round you probably just need a new rotor. pond pump flow rates

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
-
Algae Growth (Photosynthesis) ... koi ponds are usually closed recirculating aquatic systems, meaning that these systems, unlike natural ponds with streams flowing through them, lack a fresh-water flow-through source. Rather, closed recirculating aquatic systems rely on filtration to purify and reoxygenate their water. Outdoor ponds that are closed systems are subject to seasonal algae blooms and attached filamentous algae growth due to nutrient and carbon dioxide buildup. The primary nutrients of concern are nitrogen and phosphorus. Nitrogen is a by-product of decomposed fish waste, uneaten fish food and accumulated sludge in the bottom of the pond. uv size required

Winter and garden ponds. Tender marginals need to be removed wholesale. Canna lilies can be potted up and plunged into a bed in cold frames, otherwise keep them cool but frost free and dry along with all the other exotics you have been tempted buy over the last few months. Once upon a time Arum lilies (Zantedeschia aethiopica Crowborough ) and Lobelia cardinalis were treated with the same respect, but now our winters seem quite bearable to them. The more exotic looking yellow and spotty leafed Zantedeschia elliotiana , Z. pentlandii ... Store them under greenhouse staging. oxygenator pond plants

Ponds & algae concerns ...Fish ponds without adequate plantings are most susceptible to algae bloom problems. These ponds are usually well stocked with overfed fish. The absence of aquatic plants eliminates competition with algae for available nutrients in the pond water. Practical fish stocking densities and feeding must be managed closely. UV sterilization is a proven method for controlling waterborne algae. Combining sterilization with adequate biofiltration and operating the two properly is most effective in eliminating algae blooms and maintaining clear water. filters and uv light

This one sounds a bit crazy but works. Your fish will learn to recognise you especially if you feed them. To speed up this process move your hands as you approach the pond (or do something similar) ... just don't let the neighbours see you. Keep the movement the same every time. bio filter review
-
Koi will normally stop feeding around 8 degrees centigrade, 46 degrees Fahrenheit. They will lie motionless at the bottom of the pond when water gets down to about these levels. They must NOT be fed when water temperature is at these levels under any circumstances. Many serious koi keepers now heat their ponds in winter to keep their fish active and growing. water gardening and water features
