Hi,
I have a nice pond with goldfish in it. i also have a Velda Cross-Flow Biofill filter on it.
But the first chamber with japanese matting is always pretty dirty. Result is less flow inside the filter and a mess when cleaning
So i was thinking for a pre-filter. Because of the small space (and money) i can't use or buy a sieve they use on koi ponds. So i need something smaller to collect the dirt before the water reaches the filter.
here some DIY masters that made a pre-filter out of a simple bin/plastic box etc? or experience with the best results?
I am thinking of a simple plastic box with inside a plant basket and a bag. So the inlet is inside the box and outlet connected to the current filter. This idea but in a box:
