All You Need To Know About Water Gardening and Pond Keeping

This is a website that covers many aspects of pond keeping presented in short paragraph style with links to much more detailed and better presented information.

The many pages presented have been designed to create an overall impression of what good pond-keeping is about. Making sure your water garden or pond is crystal clear all year round and that it contains healthy fish and plants is your single objective ... however this situation does not occur naturally. It needs an understanding of the variables involved and correct installation of properly sized equipment. Follow these links and spend a bit of time learning about ponds and you will quickly become master.

The articles will contain many references to pond filters, pond pumps and UV lights ... these are the 3 items of equipment that are really indispensable in fish ponds.

How To Use These Links

We have extracted brief information about the page you will go to if you click the link at the end of each paragraph.

The maximum flow through a normal gravity (box type) biofilter is governed by the size of the outlet pipe from the box. Try to pump too much into the filter and you risk pumping your pond completely dry because what cannot come out of the pipe will overflow from the lid. This has happened many times. Where such a possibility exists let any overflow find its way back into the pond (eg by placing the biofilter on a slope above the pond and placing a plastic sheet between the filter and pond where possible. This will allow the water albeit maybe a bit dirty to flow back into pond ... this will save the lives of your fish. using pond filters for clean ponds
When a person builds a pond it is to achieve the vision of crystal clear water. The vision normally includes a pond full of colorful 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
A pond's ability to hold koi should not merely be regarded as a function of its physical ability to hold koi, (ie, like storing groceries in a cupboard). A koi pond's stocking rate is determined by the filter's ability to process and breakdown the waste that koi produce. To be more precise, we need to be sure we do not overstock our filter, rather than our pond. This does not merely focus on the biological activity of a filter, but also it's ability to remove solids at the required turnover rate. A pond's water quality management system would also need to provide sufficient aeration for a given stocking rate. http://www.practical-water-gardens.com/benoverstock.htm 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
Pond volume measurement ... Measure the depth using a tape or stick. Using the pond pump measure how long it takes to fill say a 5 gallons container. Now pump water out of the pond for say 5 minutes Record the depth after pumping out water The pond's volume is then calculated as follows: S = depth of pond in inches or any unit before pumping starts D = inches or any unit of water pumped out of pond when pumping stops T1 = time to fill the container T2 = time pump was run to pump out water V = volume of container ..... Volume of pond = (S x V x T2) DIVIDED BY (D x T1) waterfall pumps
A tip from Patricia in Ireland. She has a large pond with no fish. It had green algae problems. Patricia tried barley straw which took 6 weeks to work. Her tip is that to prevent the mess floating barley straw can make put it into old (or new for that matter) tights. Thanks Patricia. uv light specification
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
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
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
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
