Introduction: DIY Small Pond Filer
This Instructable details how to make a super cheap reusable pond filter. I built one to clean up excess algae and dirt floating around in my pond that the aerators stir up.
The pond filter is approximately $10 to $40 to make (depending on what glues / parts you already have, I already had a pump and glue so it was about $15 all up for me) and will last quite some time.
Step 1: Step 1: Parts List
Below is the parts list:
Bunnings:
2 x 90mm PVC Push on end caps - $2.64 (link)
1 x 1m 90mm PVC Pipe - $6.24 (link)
1 x 90mm PVC Tee Inspection Hole, threaded top - $2.20 (link)
1 x 90mm PVC threaded cap - $2.12 (link)
1 x 10 pack of domestic wipes - $2.60 (link)
1 x Araldite - $4.00 (link)
1 x PVC Cement / Glue - $3.90 (link)
EBay:
1 x Solar Powered Pump Kit - $13.39 (link)
Total Cost: Approximately $37.09
Step 2: Step 2: Building
Step 1:
Cut two 1inch lengths of 90mm pipe
Step 2:
Glue both 1inch lengths to the end caps
Step 3:
Drill 5mm holes into both end caps
Step 4:
Drill hole into Tee section to fit 12V pump electrical cable and outlet nozzle
Step 5:
Glue pump, electrical cable and outlet nozzle into place with Araldite
Step 6:
Wait for glue to dry
Step 7:
Get one wipe and cut in half
Step 8:
Put wipe into tee section and jam into place with end cap
Step 9:
Wait 48 hours before using so that glue is dry
Step 3: Step 3: Using Filter
- Make sure the filter is full of water before turning on the pump!
- When the filters get clogged you can wash the wipes in clean water and reuse them quite a number of times or you can throw them away and use more
- When removing the filter from the pond, turn it upside down and unscrew the cap. This will make sure the sludge in the pump doesn't backwash into the pond again.
- I used a 3W pump I bought from bunnings but you could use a higher powered pump for better filtering
