UV light for green murky water control ... The most effective method of planktonic algae control is ultraviolet sterilization. The many advantages of UV sterilization make it a very attractive option for algae control. First, it is a physical treatment, so it does not change the water chemistry of the pond. Second, it is very easy to install. Third, the treatment takes place outside the pond, away from the fish and plan. Chemical treatments can be successful, but they can be expensive, temporary and potentially harmful to plants and fish ultra violet lights for 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

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

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

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

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

How to select the right pond pump .. You only need this information to select right pump ... 1. Vertical height of waterfall inlet above water surface of pond (NOT bottom of pond) ... measure this in feet 2. Width of water overflow point for waterfall ... if overflow is series of smaller overflows add all together to get width in inches. If you have no waterfall choice is easier ... Waterfall Pump Selection Table ... check where height meets width in the table. This is the flow your pump model must deliver. For a wide range of guaranteed. http://www.practical-water-gardens.com/pumpselect.htm pond filter pumps

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

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
