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

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

Fish health ... One of the most important things in keeping your pond and your fish healthy is understanding pathogenic bacteria. There are a wide variety of pathogenic bacteria that can infect your pond. By far the most common are Aeromonas and Pseudomonas. These two bacteria kill more koi each year than all the other pathogens combined. Understanding how these pathogens live, eat and attack your koi is vital to controlling them. Aeromonas and Pseudomonas cause ulcers (also known as hole in the side disease), fin rot, mouth rot and tail rot. If left untreated the damage they inflict will eventually kill the fish. pond pump selection

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

Looking for a pond? If you want a stable pool environment then consider a pool with a surface area of at least 3.3 square metres or 30square feet. There may be the just the shape amongst the array of preformed pools on offer that fits your conception perfectly. On the other hand, armed with your dimensions, you will possibly find that those preformed pools stacked up in racks at the garden centre that look so vast, would seem pretty insignificant in your allotted space. Estimating the size of a flexible liner. Add double the depth to the length and breadth of the proposed size. The minimum depth ought to be 18inches to 2ft or half a metre.

If you would like to test how much water looks best for your waterfall do the following. i) Place a hosepipe into the waterfall inlet ii) Adjust the flow until you are happy with the effect iii) Without closing the hose fill a known volume container from the hose iv) Calculate the flow rate by dividing the volume of the container by the time taken to fill it. v) You can weigh the container as an alternative to knowing its volume because 1 US gallon weighs 8.83 lbs, 1 Imperial gallon weighs 10 lbs, 1 litre weighs 2.2 lbs. vi) If one hose does not deliver sufficient water then use 2 hose pipes. fiberglass water features

Vegetable BioFilters ... Aquatic Plants For Gold Fish and Koi Ponds The idea of using vegetable filters (also called veggie filters is an area where plants are deliberately grown en masse) to remove algae for Nitrate control and green water control is not new by any means. It has found use in systems where people do not want or cannot afford UV systems. Concerns expressed about vegetable filters include blocking of pump impellers by stray roots and leaves. Some plants would be worse than others ... eg water hyacinth. Despite this they are excellent nitrogen removers. An ideal plant to use is Azolla also called Fairy Moss. It grows extremely quickly and is capable of removing large amounts of nitrogen and of course carbon through photosynthesis. It is also easy to remove simply by netting in the event it over-runs the filter area. http://www.pond-solutions.co.uk/pjmvegfilter.htm water gardens and pond filters

Plants and algae in a pond compete for the available nutrients in the form of phosphorous and nitrogen containing chemicals. It follows that the more pond plants there are then the greater the probability of reducing algae blooms (green or brown murky water). Old well-planted and chemically stable ponds as a result tend to suffer less from algae problems than newly created young ponds. Yes algae are plants and blanket weed is algae. Ponds with lots of blanket weed tend to have crystal clear water. Blanket weed thrives best in alkaline (higher pH) ponds. pond algae and uv

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

Never switch off your pond pump for more
than about 60 minutes
Make sure the delivery pipe from the
pond pump is not kinked
Must the UV be placed before the
biofilter?
A waterfall adds oxygen to a pond by
creating a large surface area
Submersible pond pumps can operate
against a closed valve
It is a good idea to pump out about 10%
of your pond water
Lighting in and around ponds creates a
brand new dimension
Sick and tired of looking at debris on
the bottom of your pond?
Do not feed more food than what you fish
can eat
