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

When a person builds a pond it is to achieve the vision of crystal clear water. The vision normally includes a pond full of colourful fish and attractive aquatic plants. Often the reality of a pond is something quite different ... a green smelly hole in the ground. This need not be the case. Before you dig the hole do understand that if you intend to keep fish then a biofilter must be installed. A biofilter can be a fairly simple box shaped container with a suitable biomedia inside it onto which bacteria can accumulate so that they can do the job of purifying the pond water day in and day out. all about water garden fountains

Plants in a pond also help to reduce nitrate levels ... the nitrate is formed naturally by he action of bacteria on the excreted waste products from the fish and other aquatic animals. Nitrates are rich in Nitrogen and there is a process of conversion from ammonia excreted by fish to nitrite then to nitrate. Always spray water onto the pond surface when filling with fresh tap water ... any chlorine in the tap water will then be reduced. pond pump supplies
-
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 & Springtime ... Apart from maintenance problems, the main thing is the blanket weed, spirogya, cotton weed whatever. It is the candyfloss type of algae that gets a start on the rest of the plantlife in the pool and just loves that bright sunlight. It also loves water with a high pH. So if you reduce that with proprietary chemicals, although I have a client experimenting with vinegar, you will find that any other treatments are a lot more effective. Most aquatic suppliers have some remedy. Barley straw is effective for certain periods as long as the water is very well oxygenated and the straw is changed at regular intervals of not more than 10weeks water gardens, pond keeping

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

Measuring pond volume using science .. this is worth pointing out for its simple but brilliant bit of chemistry. Once more I am grateful to a reader for pointing this out to me. This method depends upon a pondkeeper using salt in the pond water. By measuring the salt concentration in the pond water before and after adding a known amount (lbs) of salt to the pond it is possible to calculate the pond volume very accurately and easily assuming the salt hydrometer is also accurate. If you want to know more e mail me and I will send you a calculator pond pump head or pressure

Pond and garden lighting ... A very unique and effective garden light has been newly introduced into the UK and Europe. During the day this device is a highly realistic looking rock. At night the whole rock glows with diffused light creating a magic and enchanting effect. Japanese lanterns also create magical effects. Foggers used in conjunction with lights add magical and mystical properties to pond and plants. preformed garden ponds

Algae Isnt Bad, Is It? Algae can be either beneficial or detrimental to a pond, depending on the owners viewpoint. Algae provide nutrients for newly hatched fry, and indirectly act as a color enhancer. As algae grow in a pond, a population of zooplankton will also develop, on which the fish feed. These natural live feeds help develop the intense coloration desired in most koi. Unfortunately, algae blooms prevent viewing the fish so that sick fish can go undetected for days or even weeks. pond algae and uv

Save when you buy koi food or fish food. Check your koi fish food label. Do NOT waste money. Understand the specification on koi food and fish food packets and you will save considerable amounts of money and grow bigger koi fish more quickly. Do not believe everything you are told about koi food it might not be true. Check for yourself easily. Koi Food If a 5 kg bag of koi food contains 15% ash, 10% moisture and 3% fibre then 28% of the bags contents (amounting to a whopping 1.4 kg) is a total waste of money. http://www.practical-water-gardens.com/koifood.htm pond pump selection
