Pond
Question 1: What do I need to build a pond?
You will find useful tips and suggestions for garden ponds in our catalogue or here on our web site under Wasserwelten.
In addition we recommend our video “Water in the Garden – planning and building”. It is available from the OASE Fachhändler in your area.
Question 2: Which factors do I need to consider when selecting the pond environment?
First the pond should not be exposed to direct sunshine all day long (this promotes excessive algae growth). We recommend planting all around the pond. The optimal location is half shaded and half sunny.
If there are fish the water depth should be at least 80 cm. In the ratio of water surface to depth an embankment angle of app. 30 degrees should be maintained. Give the embankment a terrace form, and provide stand areas for plant baskets.
In addition ensure that leaves cannot fall directly into the pond.
Question 3: Where can I get practical tips about building a pond?
Regular tips and practical suggestions are found in the OASE catalogue "Water gardens" or in the OASE dvd "step by step".
Question 4: What does a water analysis cost?
Water diagnosis is usually offered free-of-charge. Simply ask your local OASE aqua activ Partner . He will be pleased to advise you.
You can also get the Test-Set “OASE aqua activ” Test Set from your dealer in order to perform regular water quality checks at your home.
Question 5: Which pump is suitable for which pond?
The selection of the right pump and the appropriate accessories depends on many factors. Your OASE dealer will work out the optimal solution for your individual needs together with you.
The pond size is not the decisive factor for selecting the right pump. Rather: What should the pump be used for?
· Watercourse
· Filtration
· Fountain attachment
Question 6: How is the pond content calculated?
First the volume must be determined. For this simply use the formula L x W x H (length times width times height).
Depending on the number of flat water zones subtract approximately a third to half.
As result you will get a basic value sufficient to enable you to select the required pump or optimal filter.
Question 7: How high can a fountain be?
In general: A fountain should not be higher than the radius of the pond.
Question 8: From which point is the height differential calculated for a watercourse?
The height differential for a watercourse is measured from the water level to the upper source point.
Question 9: How much water evaporates daily in a pond?
No clear information can be provided to this question. Evaporation depends on quite a number of factors.
The location of the pond, the effects of sun and wind have substantial influence on evaporation. Also a watercourse, and particularly a fountain, promote water evaporation.
