Part of the appeal of koi keeping are the many DIY
skills we can use
There often comes the time though, after the initial
explosion of effort and enthusiasm, as the pond has had
a year or two to mature and the dust of construction has
well and truly settled, that what was once a novelty has
now become a chore.
- Linked directly to the submerged multi-chambered
filter, it works 24/7 to remove the waste that
settles in a pond.
- To be effective, a bottom drain must be fitted
- Bottom drain efficiency can be improved even
further by ensuring there is no raised lip around
the circumference of the bottom drain.
- Construct a drain in each filter chamber for
easy cleaning. A drain in each chamber will allow
you to purge a chamber at the pull of a slide valve.
- Each separate chamber should have its own
independent 4 inch drain to waste, installed flush
with the chamber floor to allow rapid and unaided
cleaning of the chamber.
- A useful tip when cleaning out chambers
constructed with a drain, is before filling the
cleaned chamber to allow clean water to run down the
drain pipe to avoid any sludge being retained in the
- This is due to the time taken to empty or clean
filter chambers, removing any residual filter media,
cleaning that, reassembling the media in the chamber
and topping up the pond.
- In a pond where plans for such a regular
eventuality have not been made, then topping up will
soon become a chore.
