Outdoor Design Considerations
If you are considering building
a large outdoor pond, don't attempt it unless you have room for the
landscaping, or it will just look out of place.
For the pond picture
below, I had quarter of a acre to play with.
The pond is 25,000
gallons, and has biotec 30 and biotec 10 filters, plus 110uv and 16000 and
12000 aquamax pumps.
The build sequence was
- Dig the pond out
- Then plant the vegetation, including the trees
- Then install the filters
- Then put the pond liner
- Lastly add the water and surrounds, including the bridge in that order


The pond pictured below is
38,000 gallons. It has 2 biotec 30 filters, 2 aquamax 30000 pumps, 2 110uvs and
an airblow 80 driving a large air block in the pond.
The pond is semi
natural which, as you can see with its position, any other would have looked
out of place.
The large gallonage enables the pond to support koi.
There's an anti heron electric fence around pond and decking well away
from waters edge. I had one acre to play with, and built it using the same
routine as the first pond on this page.
