  • Fish Loading Calculator
    This calculator will help you to identify exactly how many fish your pond will hold to prevent problems associated with over stocking.
  • Calculate Pond Volume - Regular Shaped Garden Ponds
    Remember that it isn't essential to be 100% accurate when calculating pond volumes. However it is important to have a good estimate of the amount of water in your fish pond pond or water garden. This calculator has been designed to help you get things right.
  • Calculate Pond Volume - Irregular Shaped Fish Ponds
    This calculator employs the counting squares method to aid in calculating your pond volume. It is important that you have a fairly accurate idea of the actual volume of water in your garden fish pond so as to avoid choosing an incorrectly sized pond filter or pond pump. It is however not essential to be 100% accurate. 95% is fine.
  • Pump Power Consumption
    This calculator allows you to compare the total running cost of two pumps over a 3 year period. Simply take the purchase price and add it to the total running cost to see which is the best option.
  • SaveMoneyRun2Pumps
    Most fish ponds have a waterfall and need a biofilter. It is normally the case that the basis upon which a pump is specified in this kind of situation is on the needs of the waterfall and not the biofilter. Generally the flow down a waterfall is more than that required by a biofilter. By understanding this it is possible to save money. A biofilter needs water 24 hours per day but a waterfall can be switched off whenever it suits the pond keeper. Hence a small pump can be used 24 hours per day and the larger waterfall pump as many hours as you choose.
  • Complete Pump Selector
    This program will calculate the total pond pump head required for your pond system in US measurements, UK measurements and metric measurements. Simply open up the spreadsheet and fill in the required columns. This will be of benefit to pond keepers anywhere.
  • Pump Flow Rate Conversion
    This helpful tool will calculate the gallons/min (US & UK), Cu feet/min, Liters/min, CU Meters/min and Lbs water/min. All you have to do is enter the correct figure in the column provided.
  • Koi Food Economics
    This calculator asks you to enter various koi food parameters such as the total weight, percentage ash, percentage moisture and the cost. From this it calculates the percentage of wasted money. Use this tool to ensure you buy quality koi and goldfish food and save money in the process.
  • Short Fat Pipes Are Best
    This calculator has been designed to assist with understanding pump selection and the extra head required to overcome pressure drop (friction loss) when water flows through a pipe. This is important concept when designing for accurate pump specification. Pipe diameter is critically important and you should always minimize pipe length and maximize pipe diameter. In this way the head loss due to friction is minimized. It does not matter if pipe is inclined or flat or going downhill the same principle applies
  • Size Your Pipe
    Calculation will allow you to estimate the head loss (pressure drop) in a pipe with a nice clean internal surface. In general head loss is higher in small diameter pipes and long lengths of pipe. Diameter is the greater of the 2 impacts.
  • Volume & Weight Conversions
    This calculator works out pond volumes and weights for you in US measurements & weights, UK measurements & weights and metric.
  • Waterfall Flow Rates
    This calculator works out the flow rate required in order to supply a waterfall lip of various widths. Obviously a wider lip requires more water to pumped to it in order to maintain the desired effect. This tool shows the lip width in both inches and cm's and the volume flow rate per minute in US gal, UK gal & metric liters.
