              POND FILTERING

Optimizing Koi pond bead filtering systems

Basic   Intermediate  Advanced 

Bringing clean water through to your pond....

Which filtering systems and design features are best for your pond and budget? The following information with illustrated filtering and plumbing diagrams will provide you with a clearer understanding of typical lay out sequence of many different filtering components ... All designs are utilizing one or more pumps to move water through the filtering systems that incorporate the pressurized bead filter and an Ultraviolet light (U.V. light).

Our bead filters literally takes advantage of all the latest technology in bead filtration and offers both an extremely efficient mechanical and biological filter all in one.

• Pond design basics! 

Lets quickly cover the basics! A well designed Koi pond should have certain features since they are key to the remaining filtering system components. First you must mechanically attempt to remove crud before attempting to biologically begin to filter the chemicals. Then with the water being free of crud and chemicals, you are set to perform the final filtering stage sterilization. U.V. lights perform this function quit well. At some point before or after the water returns to the pond, the water should be replenished with oxygen. Water features perform this for us quit nicely with the added bonus of soothing us with the sites and sounds of trickling clean water.

Skimmer - It would be pretty tough to find a swimming pool without a skimmer, and for good reasons! Removing leaves and dirt from the surface is the start to mechanically filtering any pool or pond. The skimmer removes more then just leaves and dirt that settle on to the surface. A skimmer also will skim off the “dissolved organic compounds”. Dissolved organic compounds will form in any pond and if not removed causes a film of bubbles on the surface or around the ponds edge. A skimmer removes this film by constantly skimming off the top surface of the pond. A skimmer can make the difference in your overall filtering and you enjoying your Koi pond. So install a skimmer!

Bottom Drain - Once again, ever see a swimming pool built without a bottom drain? The ponds bottom drain does much more then mechanically remove bottom crud and Koi fish waste, it also brings the much needed oxygen down to lower levels in deeper ponds. It draws the lower water columns out to be replaced with the new fresh filtered water returning to the pond. Good circulation prevents stagnant water, benefits the fish, your ponds appearance as well as the filtering system. Install at least one bottom drain or more if your pond size warrants more.

• Mechanically filtering.

Once the water is removed from the pond, it is now necessary to begin the filtering process. The first stages of filtering is the removal of debris and or crud. Referred to as Mechanical filtering. This effects the remaining filtering components. For the better the mechanical filtering is performed, the easier it is on the remaining filtering system to operate optimally. Two components that do this for you is the skimmer and the leaf trap or filter basket on the water pump. Elementary as this may be, it can trap debris 1/8 inch in size and larger. If this debris were able to continue on into the pump, you would be enslaved into constant maintenance of cleaning a plugged up pump housing. More on pumps later.

Trapping debris down to 1/8 is only a start. The filter itself is capable of also mechanically trapping crud. The more crud the filter is required to trap, the tougher it is for the filter to be processing the biological chemical portion of the filtering system. Over sizing your filter can help to over come  this. Yet, the filtering system can be optimized to perform better by improving on all stages of the filtering system. If we were attempting to achieve the simplest of design, and budget permitting, then we would have the following minimum Koi pond filtering system shown in the diagram below.

Brief note about U.V. Light installation UV lights require either the inlet/outs be installed face up or the unit installed vertical. This provides complete chamber filling and for air to be flushed out in order for the unit to operate properly. All of the diagrams show the U.V. Light mounted is such a way that would not permit the air to be flushed out. The diagrams are for understanding concepts.

 

 

BDS-PFL - Simply defined is Bottom Drain, Skimmer - Pump, Filter, Light
This naming convention is needed for the remaining articles in the comparison and description of the diagrams. You will see as we continue to modify the filtering system, this will help understand more quickly what components any diagram may have when compared to other diagrams. The 3 main components in BDS-PFL when figured for a 2-3000 gallon pond could retail around $2,500.00 - Artesian 1/4 hp pump, a Bead filter, Emperor Aquatics 40 watt U.V. Light.

    3-way valve that helps control flow from different sources.
    Check valve that permits flow in one direction only.           

Notice also that the location of the U.V. Light is after the filtering of the water. This is the ideal location since it will perform much better with crud removed from the water during the previous stages. Find the clean out labeled in any of the diagrams. It is placed at the end of the bottom drains pipe which is usually done in 3 inch or 4 inch pipe. The clean out is nothing more then a T fitting with a threaded plug in the top. It has the larger opening on one end and has a 2" reducer for the remaining plumbing pipes. Should a pile of crud or leaves begin to plug up at this point due to the reducer fitting, simply turn off the pump and remove the cap and clean out the blockage. * Use of a 4 inch knife valve just in front of the clean out will make it easier when opening the plug. Easier by shutting off the water supply from the pond.
