GIDGEGANNUP REVISIT
We revisited this awesome big boulder pond back in late April for its first annual wetland filter backwash.
It’s looking fantastic and the water is so, so clear 💦💦💦
This is the one where we needed to get a crane in to lift and place about half a dozen of the big boulders. One of the boulders in the waterfall weighed in at 7.2 tons!!! HUGE 🪨
The filter was a bit dirty as you’d expect for an exposed pond like this after twelve months, but that is exactly their purpose. And the serviceability of an Aquascape upflow constructed wetland filter is one of its best traits.
The system of a vertical ‘snorkel’ and horizontal dispersal ‘centipedes’ are the real keys to this serviceability. Enabling us to backwash built up sediment from the graded stone/gravel filter media and very easily pump out remove it from the wetland filter and pond system in a very water efficient way.
