Pond Information

Pond Information

When you plan the pond location, it is best to avoid under trees as leaves, branches and bird droppings cause problems. Remember to include room for a filtration system and plumbing. Filters can be operated as either gravity or pumped systems. Gravity systems are located below the pond elevation and deliver water to the filter without pumping, but require pumping to return water to the pond. Pumped systems require pumps to deliver water to filtration, and the water returns to the pond by pump flow or gravity. For planning purposes, the differences are that gravity flow systems may require burial of the filter system, or that the filter be placed downhill of the pond if the pond location is on a slope. If you plan for a gravity filtration system, make sure the filter is not so far below the pond that the pond will completely drain if the filter pump is not operating. Gravity systems have the stated advantage of placing any pumps behind the filtration system. When the pumps are behind the filters, it provides a better opportunity to capture solids before they are disrupted by passage through pump impellers. In theory, gravity filtration systems should be more efficient at solids removal. However, fish wastes are not compact solids, and most of the particulate material in ornamental ponds will be in the form of suspended plant materials, usually clumps of algae. Algae cell volume is much smaller than the impeller clearance in water pumps. Algae removal usually occurs through settling or by attachment to the biofilm on filter media. Regardless of the filtration system chosen, make it as close to the pond as feasible to avoid water velocity loss from friction or accumulation of materials within the piping.

Pond Setup 

One of the big problems is when people build ponds with a flat bottoms. Waste tends to lay in lazy corners. This may cause bad bacteria to form, which is harmfull for your fish. Your pond should be designed with slopping bottom. This will enable the waste to settle at the lowest point where a submersible pump or a bottom drain will remove the waste from your pond.

 

 Building a Pond

Over the coming weeks I will be reporting on a new pond being built. I will be uploading photos and as much helpful information as possible. This will have everything from start to finish including problems that may occur to even costings.






First you mark out the shape of your pond using a can of spray paint and check the levels. We than got in a operator of a Dingo to dig and remove the soil for our pond. Luckily we have mainly sandy soil. If you have hard soil like clay you will need a bigger machine to do the job. 



Tell your machine operator to be careful if the pond area is near buildings as there could be plumbing or electrical wires below the ground. Yes of course, we found an electrical cable as you can see in the above photo. This means we need to get an electrician in to divert the cable around the pond . 



Soon to be continued.
