Lighting in and around ponds creates a brand new dimension and attraction to the garden. Normally for safety reasons these are low voltage. Lights can be submerged or above the water surface to create immediate impact and variation. You have submerged colored lights normally pointing up to the surface of the water. These could also be plain white light of course. Others focus the light down onto the bottom of the pond by creating a mushroom or umbrella effect. Still others float around the surface encased in glass globes. koi ponds and koi fish

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

Fish ponds and winter ... Koi keepers know that fish will still come to be fed, if feeding is a routine, way past the temperature at which they are capable of digesting food. Being cold-blooded animals their systems can only summon enough reserves to digest very low protein foods between about 10C (50F) and 7C (45F). So only feed a little winter feed or maybe a wheat germ based food two or three times a week. Below that temperature, feed nothing at all. As the temperature of water in the pool drops to around 5 C (41F) the fish begin to hibernate. Arm yourself with a thermometer that will register these temperatures accurately so you wont have to guess what is going on. water gardens, pond keeping

Winter water gardening ... If the frosts are slow to arrive, the foliage factor from some of the variegated water plants is a major bonus. The sword like leaves of the Iris laevigata Variegata, the variegated scented rush Acorus calamus Variegatus or the small tufty A. gramineus Vareigatus are late to die down and are up early spring, brightening up the most moribund boggy patch. Gardeners garters (Phalaris arundinacea var. picta) add a splash of colour all year, but are somewhat rampant and difficult to contain after the first year floating pond plants
-
Too much algae in pond .... Beware algae blooms in ponds. Let's equate this to what living organisms do in the pond. Think of the flora and fauna as exhaling carbon dioxide while inhaling oxygen during the night. From this you will agree that dawn is the critical time in a pond. Often people wake up to find dead fish and wondered what happened. Such deaths could be associated with very low oxygen levels coinciding with high carbon dioxide levels. When ponds are full of suspended algae such problems can arise. pond algae

A biofilter is absolutely essential if you want to keep fish in a pond. In my opinion it is cruel not to install a biofilter since without a biofilter the fish will live in a potentially highly toxic environment. A biofilter will automatically start itself up once fish are introduced into a pond. Nitrosomonas and Nitrobacter are naturally occurring and will rapidly find their own way into the filter. They then need oxygen from circulating water as well as excreted ammonia from the fish (this occurs naturally) to thrive and multiply. It will take some considerable time for the biofilter to reach maturity. pond filters

If you want to save money and reduce dramatically the risk of pond infections and fish disease do NOT use a sand filter for a pond. They are great for swimming pools, and bad for ponds. The basic reason is that many "dead-spots" are created because the water makes channels in the bed of sand. All water then flows through these channels and all the other sand becomes de-oxygenated. This situation allows anaerobic bacteria to grow (those that grow in absence of oxygen ... normal these cause bad smells). Anaerobic bacteria create pathogenic conditions in a pond. koi pond filters

Measuring pond volume in USA .... Burt Ballou pointed out that in USA most homes have a water metre which can be accessed readily. This makes pond volume measurement simple if you start with an empty system. Just make sure that while filling the pond nobody uses the toilet, takes a shower does the washing up etc. All you have to do is then record the start and finish readings from the metre to get a very accurate indication of pond volume. fountain pumps
-
Sponges in pond pumps ... 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. So long as you keep this type of pump away from heavy debris on bottom of pond (stand the pump on a brick for example) you will get away with removing the sponge permanently ... although such use would nullify the pump's guarantee. The sponge is there to protect the impellor form debris damage. fountain pumps
