Pond Cleaning
All fountains, ponds and waterfalls collect debris such as leaves, loose dirt and grit over time. Larger and heavier matter will tend to sink and collect at the bottom of the pond. Koi and fish ponds are notorious for becoming dirty or polluted over time with particles of food, fish waste, dead scales, etc..
Two types of devices are typically used concerning pond care (shallow ponds and waterfalls):
Vacuum pump devices are effective in collecting debris from water surfaces; however, these devices are not able to effectively collect accumulated debris from the bottom of a pond. These pumps enhance the aesthetics of the water surface and can assist in helping the skimming function.
Hand operated pumps are able to draw water and debris into a tube through the open lower end. A filter for removing debris from the water drawn into the device is provided in the lower end of the tube. These devices tend to be most effective in shallow pond applications to remove debris from the base of the pond. Hand operated pumps are usually pretty inexpensive.
Other pond care devices mostly use suction to draw liquid and debris into the device and then filter the debris from the liquid before returning it to the water mass. In example water and debris is drawn into a collecting chamber then water flows back out through the filter when the device is withdrawn from the pond; the debris is trapped on the filter at the lower end of the chamber. Filters can quickly become clogged thus it is necessary to disassemble and clean the system frequently to remove debris.
For ponds and waterfalls we recommend both inexpensive vacuum and hand operated pumps concerning pond care.
