Pond and Liner Size
It's important to work out the amount of water
your pond will hold and the size of liner you'll
need. Use our handy guide to help with this.
Alternatively go to our website and use the
pond calculator or just give us a call!
Measuring your pond
To get an accurate measurement
of depth, place a piece of wood
or a broom across your pond
and measure from that to the
bottom of your hole.

What Size Pump and Filter will I need?
A pond with lots of plants and no fish (or a few, small native
fish) needs all of the water to be pumped through the filter
every 2 hours.
We call this a nature pond.
A pond with some plants and some fish (mainly goldfish),
needs all of the water to pass through the filter every 1
½
hours.
We call this a goldfish pond, it is by far the most
common type.
A pond with few plants and big fish, like koi, needs the
water to be pumped every hour.
We call this a koi pond.
So if you have a pond of 3000 litres then your pump flow
rate will need to be:
Nature Pond – Flow rate is 1500 litres per hour
Goldfish Pond – Flow rate is 2000 litres per hour
Koi Pond – Flow rate is 3000 litres per hour
Once you've worked out your pump flow rate turn to page 28
to choose a pump or if you have any questions give us a call.
