My Free to use Pond Water volume calculator. Start by just entering the dimensions of your pond in mm, cm, inches or feet. The free tool will give you the approximate amount of water in gallons or litres.

Use my free Pond Liner size calculator to ensure you choose the correct size liner. Remember it's always better to purchase a pond liner that is larger than than you need to allow for shelves and uneven ground.

Calculate the running costs for using your Pond Pump 24 hours a day. My tool will automatically calculate the daily, monthly and yearly costs based on the current UK Standard Energy Tariff.

The running costs for UV pond filters will vary depending on the overall wattage of your UV lamp. High watt UV lamps will be more effective in keeping your pond clear at the cost of an increased electricity bill.
